The issue is that libvirt only advertises KVM if it finds a file named qemu-kvm or kvm, so it won't by default allow using kvm with a stock qemu release. You can probably work around this by symlinking /usr/bin/qemu-kvm to /usr/bin/qemu-system-x86_64. Might want to file a bug with your distro to do the same (or have them actually ship the forked qemu that is distributed with KVM upstream, since it's generally what receives the most testing). The proper fix though is to have libvirt advertise KVM for upstream qemu binaries if it finds the correct CLI arguments. We will probably need to do this anyways when the KVM qemu fork is fully merged upstream. - Cole > root@horus /home/florian # virsh --connect qemu:///system capabilities > <capabilities> > > <host> >

[libvirt] [PATCH 0/3] Support for marking domains as "tainted"
by Daniel P. Berrange 05 May '11

05 May '11

There are various configurations for virtual domains that we allow, but do not wish to actively support in production environments. The support situation is similar to that of binary only or non-GPL kernel modules, so borrow the kernel's idea of "tainting". When an undesirable configuration is used on a running VM, set a suitable taint flag and log a warning. OS distro bug triagers can see these warnings and decide whether to support users filing bugs in this scenarios

[libvirt] [PATCH] Fix qemuMigrationToFile nonull annotation
by Daniel P. Berrange 05 May '11

05 May '11

The qemuMigrationToFile method was accidentally annotated for the 'compressor' parameter to be non-null, instead of the 'path' parameter. Thus GCC with -O2, unhelpfully deleted the entire 'if (compressor == NULL)' block of code during optimization. Thus NULL was passed to virCommandNew() with predictably bad results. * src/qemu/qemu_migration.h: Fix non-null annotation to be against path instead of compressor --- src/qemu/qemu_migration.h | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) This shows that the 'ATTRIBUTE_NONNULL' annotation is actually really very dangerous to use. GCC is incapable of issuing any warnings about callers passing NULL, unless they pass a literal "NULL". If the caller does 'void *p = NULL; foo(p)' it will not warn. GCC is also not warning about the fact that there is a huge block of code for 'if (compressor == NULL)' that is "dead" code and being deleted. While it is perhaps nice to have ATTRIBUTE_NONNULL for static analysis tools like clang, IMHO, it is too dangerous for us to continue to have it enabled in builds. I think we should define it to a no-op macro, unless explicitly enabled with configure. diff --git a/src/qemu/qemu_migration.h b/src/qemu/qemu_migration.h index f4e86c8..c0f3aa2 100644 --- a/src/qemu/qemu_migration.h +++ b/src/qemu/qemu_migration.h @@ -64,7 +64,7 @@ int qemuMigrationToFile(struct qemud_driver *driver, virDomainObjPtr vm, int fd, off_t offset, const char *path, const char *compressor, bool is_reg, bool bypassSecurityDriver) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(6) + ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_NONNULL(5) ATTRIBUTE_RETURN_CHECK; #endif /* __QEMU_MIGRATION_H__ */ -- 1.7.4.4

[libvirt] Keep qemu capability data for each VM from startup
by Daniel P. Berrange 05 May '11

05 May '11

Currently, whenever we require QEMU capabilities data, we rerun QEMU to extract the info. This isn't desirable because it is inefficient and the QEMU binary may have changed since we started the guest. This series makes us keep a copy of the capability data around for lifetime of the VM process

Hi, I try to use VT-d, but meet with a strange problem . I create a VM through "virsh create ***.xml",as follows: root@shahe26:~# virsh create vt_d_debian.xml Domain vt_d_debian created from vt_d_debian.xml root@shahe26:~# virsh list Id Name State

[libvirt] qemu qxl video memory parameter - windows bsod with spice
by Emre Erenoglu 04 May '11

04 May '11

Hi, Please see the below discussion with the spice community. libvirt is adding a parameter about video ram to qemu process and this parameter might be responsible of a crash in the qxl at higher resolutions. Spice people tell me that their default ram should be 64 Mbytes. I'm using libvirt 0.9.0 and qemu 0.14, virt-manager 0.8.7. When configuring a guest in virt-manager, cirrus driver is added as default, then you can change it to qxl, but the 9 MB videoram parameter can't be adjusted and it does not automatically change to 64 MB. If you add a 2nd qxl video card, then it has 64 MB memory. The parameter that qemu gets with one qxl device is: -vga qxl -global qxl-vga.vram_size=9437184 The parameter that qemu gets with a second qxl device is: -vga qxl -global qxl-vga.vram_size=9437184 -device qxl,id=video1,vram_size=67108864,bus=pci.0,addr=0x8 Is this a bug in libvirt or other related tools?

Well, this parameter is not configurable from the virt-manager UI and it configures 9 MB to the command line of qemu by libvirt (even latest 0.9.0) version. When you add a 2nd VGA adapter, it adds 64 MB to that adapter correctly (-device qxl,id=video1,vram_size=67108864,bus=pci.0,addr=0x8) I guess i need to file a bug report to libvirt too. Emre

[libvirt] [PATCH] remote: avoid null dereference on error
by Eric Blake 04 May '11

04 May '11

Clang found three instances of uninitialized use of nparams in the cleanup path. Unfortunately, one is a false positive: clang couldn't see that ret->params.params_val is guaranteed to be NULL unless allocated within a function, and that nparams is guaranteed to be assigned prior to the allocation; hoisting the assignment to nparams to be earlier in the function shuts up that false positive. But two of the reports also happened to highlight a real bug - the error path can dereference NULL. * daemon/remote.c (remoteDispatchDomainGetMemoryParameters) (remoteDispatchDomainGetBlkioParameters): Don't clear fields if array was not allocated.

[libvirt] libvirt tracking of hung/stopped QEMU VMs
by Ryan Harper 04 May '11

04 May '11

I've encountered an interesting scenario: 1. define a guest via virsh define <xml> 2 start this guest via virsh 3. one of the disk elements is a multipath device that is currently misconfigured such that any io to the device hangs the calling process 4. libvirt times out when attemping to communicate via the monitor to the guest (btw, this timeout isn't configurable AFAICT) 5. returns an error from create indicating that we failed to create the VM At this point: 1) libvirt reports that the VM is stopped (and this is true, the qemu process has never been issued the 'cont' command and thus won't ever execute gues tcode) 2) the qemu process for this VM is still running (just blocked on IO) 3) it is possible that if the process becomes unblocked that the QEMU process will be functional again, but won't be started, and the process won't be terminated since libvirt isn't tracking this any more, and is consuming some amount of resources that are allocated on start up. How can we clean up from this failure scenario? Would it make sense for libvirt to send a SIGTERM to a qemu if it failed to create? In the above scenario, this would allow us to reap the process if it ever became unblocked. -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx ryanh(a)us.ibm.com

[libvirt] [PATCH] qemu: avoid null pointer dereference
by Eric Blake 03 May '11

03 May '11

This code has had problems historically. As originally written, in commit 6bcf2501 (Jun 08), it could call unlink on a random string, nuking an unrelated file. Then commit 182a80b9 (Sep 09), the code was rewritten to allocate tmp, with both a use-after-free bug and a chance to call unlink(NULL). Commit e206946 (Mar 11) fixed the use-after-free, but not the NULL dereference.

[libvirt] Libvirt and IPSec (was: What about Trusted Virtual Domains???)
by Paolo Smiraglia 02 May '11

02 May '11

Hi to everyone! First of all, sorry for the thread subject change. Due to the several issues of the Libvirt implementation of the Trusted Virtual Domains (TVD), I decided to approach the topic in a modular manner. I think that the first step should be to define the IPSec support or, more in general, the secure tunnel support for Libvirt. I see the implementation divided in two step: 1. define a new driver called 'sectunnel' which describes a generic secure tunnel that will be established using several technologies (for now using only ipsec) 2. modify the existing 'network' driver by adding the possibility to specify the 'sectunnel' that the network have to use in the virtual network definition As an example, you can see below a possible XML definition of the network which use a secure tunnel and the corresponding 'sectunnel' XML definition: NETWORK DEFINITION ================== <network> <name>sec-net</name> <uuid>3e3fce45-4f53-4fa7-bb32-11f34168b82b</uuid> <bridge name='virbr0' /> <domain name='example' /> ... <sectunnel name='sec-tun' /> <--(specify the 'sectunnel' to use) </network> SECTUNNEL DEFINITION ==================== <sectunnel type='ipsec'> <name>sec-tun</name> <uuid>8b7fd1b0-4463-43b7-8b6e-8006344aeb66</uuid>  <sa> <secret uuid='...' /> <--(specify the 'secret' which contains the pre-shared key) </sa>  <sp> <src_range address='10.0.0.1' prefixlen='30' port='5000' /> <dst_range address='10.0.0.2' prefixlen='30' port='5000' /> <upperspec protocol='any' /> <policy direction='out' action='ipsec'> <rule protocol='esp' mode='tunnel' level='require'> <src address='192.168.0.1' port='55055' /> <dst address='192.168.0.2' port='55055' /> </rule> </policy> </sp> <sp> <src_range address='10.0.0.2' prefixlen='30' port='5000' /> <dst_range address='10.0.0.1' prefixlen='30' port='5000' /> <upperspec protocol='any' /> <policy direction='in' action='ipsec'> <rule protocol='esp' mode='tunnel' level='require'> <src address='192.168.0.2' port='55055' /> <dst address='192.168.0.1' port='55055' /> </rule> </policy> </sp> </sectunnel> As you can see in the 'sectunnel' XML definition, I use a 'secret' element. This element is a Libvirt secret [1] and it stores the pre-shared key used by IPSec to establish the Security Associations (SA). Obviously this feature requires to define a new usage category in the 'secret' driver definition. Another possible way to establish the SA is to use the X.509 certificates. To this purpose, I think that the certificates already used by Libvirt to setup SSL/TLS remote connections, might be used. That's all! :-) What do you think about this possible IPSec implementation? Thanks in advance for the replies!

[libvirt] RFC: virInterface change transaction API
by Laine Stump 02 May '11

02 May '11

I've been asked to implement what some people have termed as a "transaction-oriented" API for host interface configuration (ie virInterface*()). The basic intent is to allow rollback to a known-good config if anything goes wrong when changing around the host network config with virInterface*() functions. The most straightforward way to achieve this is that prior to calling virInterfaceDefine/virInterfaceUndefine, the current state of the host's network configuration (ie the /etc/sysconfig/network-scripts/ifcfg-* files in the case of Fedora and RHEL) would be saved off somewhere, and kept around until we're sure the new config is good; once we know that, we can just eliminate the backup. If, however, the user of virInterface*() explicitly requests, we could copy the files back; alternately if the system is rebooted without these known-good files being erased, we would assume that something went wrong and restore the original config. As with all other virInterface functions, the details of all this will be handled by netcf (and below), but since libvirt is the main consumer of netcf, I figure this is the appropriate place to discuss how it gets done, so please let me know any opinions on any piece of this. I plan to start the implementation "soon", as I want to be finished before the end of May. I see 3 layers to this: 1) libvirt At the libvirt layer, this feature just requires 3 new APIs, which are directly passed through to netcf: virInterfaceChangeStart(virConnectPtr conn, unsigned int flags); virInterfaceChangeCommit(virConnectPtr conn, unsigned int flags); virInterfaceChangeRollback(virConnectPtr conn, unsigned int flags); For the initial implementation, these will be simple passthroughs to similarly named netcf functions. (in the future, it would be useful for the server side of libvirt to determine if client<->server connectivity was lost due to the network changes, and automatically tell netcf to do a rollback). 2) netcf The netcf api will have these same three APIs, just named slightly differently: ncf_change_start(struct netcf *ncf, unsigned int flags); There are two possibilities for this. Either: A) call the initscript described below to save all config files that might possibly be changed (snapshot_config) or B) set a flag in *ncf indicating that all future calls to netcf that would end up modifying a particular config file should save off that file *if it hasn't already been saved*. (A) is simpler, but relies on the initscript having exact/complete matching knowledge of what files netcf may change. Should we worry about that and deal with the complexities of (B), or is (A) good enough for now? ncf_change_rollback(struct netcf *ncf, unsigned int flags); Again, two possbilities: A) a) save the config of all current interfaces (in memory) b) call the initscript below to restore the config to its original state. c) compare the new config to the old, and: * bring down any interfaces that no longer exist (PROBLEM: once an interface has no config files, you can no longer operate on it with "ifdown") * bounce any interfaces that have changed * bring up any interfaces that have been re-added or B) a) ifdown all interfaces b) call initscript to restore previous config (rollback_config) c) ifup all interfaces. (A) is much simpler, but may lead to unnecessary difficulties when we bounce interfaces that didn't really need it. So, the same question oas for ncf_change_start() - is the more exact operation worth the extra complexity? ncf_change_commit(struct netcf *ncf, unsigned int flags); The simplest function - this will just call the initscript to erase the backup (commit_config). 3) initscript This initscript will at first live in (be installed by) netcf (called /etc/init.d/networking-config?), but hopefully it will eventually be accepted by the initscripts package (which includes the networking-related initscripts), as it is of general use. (Dan Kenigsberg already already took a stab at this script last year, but received no reply from the initscripts maintainers, implying they may not be too keen on the idea right now - it might take some convincing ;-) https://fedorahosted.org/pipermail/initscripts-devel/2010-February/000025.h… It will have three commands, one of which will be called automatically by "start" (the command called automatically at boot time): snapshot_config This will save a copy of (what the script believes are - is this problematic?) all network-config related files. It may or may not be called by netcf (see the notes in ncf_start_change() above. If this function finds that a snapshot has already been taken, it should fail. rollback_config (automatically called from "start" at boottime) This will move back (from the saved copies) all files that were changed/removed since snapshot, *and delete any files that have been added*. Note that this command doesn't need to worry about ifup/ifdown, because it will be called prior to any other networking startup (part of the reason that netcf will need to deal with that). I notice that Dan K's version saves the modified files to a "rollback-${date}" directory. Does this seem like a good idea? It's nice to not lose anything, but there is no provision for eliminating old versions, so it could grow without bound. commit_config This will just remove all the files in the save directory. So, the two problems I have right now: 1) Do we accept the inexact method of just saving all files that match a list of patterns during *start(), then in *rollback() erasing all files matching that pattern and copying the old file back? Or do we need to keep track of what files have been changed/removed and added, and copy back / delete only those files during rollback? (A version control system would keep track of this rather nicely, but that's too complex for something that's intended to be a failsafe (and that we would also like to eventually be in the base OS install). Dan B. at one point suggested using patchfiles if I wanted the save info to keep exact track of which files would need to be replaced/deleted on rollback, but on further thought this turns out to not be workable, since we would need to run diff (to create the patchfile) after all changes had been made, and any outside changes to any of the files would leave the patchfile un-appliable, thus causing our "failsafe" to fail :-( ). Therefore, we will need to rely on the list of globs to tell us what files need to be deleted, or keep our own list in a separate file.) 2) Is it going to be okay to ifdown all interfaces prior to the rollback, and ifup all interfaces afterwards? Or must we compare the new config to the original, and ifdown only those interfaces that had been previously added/changed, then ifup only those interfaces that had been previously removed/changed? 3) If anyone has ideas on making the initscript more palatable to the initscripts people, please speak up! :-) (one comment from an initscripts person was that 1) for the general case it would be difficult to draw the line on what parts of network connectivity should be included in this rollback functionality, and 2) at some point this becomes a general system config problem, and would really be better addressed by a general system wide config management system. These are both concerns that need well qualified answers. (I tend to think that this is intended as a failsafe to prevent unreachable systems, so it should be as simple as possible, and thus shouldn't be burdened with the complexity of a full system config management system (which could also co-exist at a higher level), but better answers are welcome.)

[libvirt] [PATCH v3 0/5] Add TXT record and hosts support for DNS service and dnsmasq command-line regression testing
by Michal Novotny 02 May '11

02 May '11

Hi, this is the patch to introduce the TXT record and DNS hosts support for the DNS service on the virtual network. This can be defined using the txt-record subelement in the dns element of the network XML description. The definition of TXT record names containing spaces is rejected with the error message that TXT record names in DNS doesn't support spaces. Also, regression testing for the dnsmasq command line has been added to test whether the dnsmasq command-line is correct or not. The new XML definition syntax is: <dns> <txt name="example" value="example value" /> <host ip='192.168.122.1'> <hostname>gateway</hostname> <hostname>host</hostname> </host> </dns> Where multiple host elements can be defined to put the aliases. The <dns> element have to be present on the <ip> level, i.e. one level upper than it was in version 2 of the patch since the definition affects all the IP addresses on the network. The patch series has been tested for the configuration and it was working fine and also RelaxNG schema with the tests have been both altered to add test cases to test those patches. All of the patches passed the all the tests and everything was working fine.

Are you volunteering to write some code? :-) There have been requests for both, and both should eventually be done, so I guess pick whichever one you like better :-) (since there's already a patch for VDE, albeit with different XML than we'd like, that may be quicker to finish.)

Once we get into these kinds of questions, it's probably best to switch to the developers' list (libvir-list(a)redhat.com) to get better exposure to people writing the code. I'm Cc'ing this message there (and switching the Reply-To: as well). In particular, I recently send an RFC to libvir-list proposing an expansion of the <network> XML to remove the hard-coded connection between guest interface and host interface for macvtap (type='direct') interfaces: https://www.redhat.com/archives/libvir-list/2011-April/msg00591.html and in a followup message showed how we could expand on this work to provide support for openvswitch (or vde): https://www.redhat.com/archives/libvir-list/2011-April/msg00640.html I'm planning to have this code finished and tested within the next two months at most (hopefully considerably earlier). If you're interested in implementing a <network type='openvswitch'> or <network type='vde'> you should subscribe to libvir-list (if you aren't already) so that you can follow along. > > Robert > > On 04/06/2011 04:13 PM, Robert Šmol wrote: >> >> >> On 04/06/2011 04:00 PM, Nicolas Sebrecht wrote: >>> The 06/04/11, Robert Šmol wrote: >>>> On 04/06/2011 10:34 AM, Nicolas Sebrecht wrote: >>>>> The 05/04/11, Robert Šmol wrote: >>>>> >>>>>> I would like to ask about status of VDE and libvirt.

[libvirt] [PATCH v2] util: Simplify hash implementation
by Jiri Denemark 29 Apr '11

29 Apr '11

So far first entries for each hash key are stored directly in the hash table while other entries mapped to the same key are linked through pointers. As a result of that, the code is cluttered with special handling for the first items. This patch makes all entries (even the first ones) linked through pointers, which significantly simplifies the code and makes it more maintainable. --- src/util/hash.c | 294 +++++++++++++++++-------------------------------------- 1 files changed, 92 insertions(+), 202 deletions(-) diff --git a/src/util/hash.c b/src/util/hash.c index fc7652d..dbb34ec 100644 --- a/src/util/hash.c +++ b/src/util/hash.c @@ -50,14 +50,13 @@ struct _virHashEntry { struct _virHashEntry *next; void *name; void *payload; - int valid; }; /* * The entire hash table */ struct _virHashTable { - struct _virHashEntry *table; + virHashEntryPtr *table; int size; int nbElems; /* True iff we are iterating over hash entries. */ @@ -165,7 +164,7 @@ virHashTablePtr virHashCreateFull(int size, * * Create a new virHashTablePtr. * - * Returns the newly created object, or NULL if an error occured. + * Returns the newly created object, or NULL if an error occurred. */ virHashTablePtr virHashCreate(int size, virHashDataFree dataFree) { @@ -189,10 +188,8 @@ virHashTablePtr virHashCreate(int size, virHashDataFree dataFree) static int virHashGrow(virHashTablePtr table, int size) { - unsigned long key; int oldsize, i; - virHashEntryPtr iter, next; - struct _virHashEntry *oldtable; + virHashEntryPtr *oldtable; #ifdef DEBUG_GROW unsigned long nbElem = 0; @@ -217,43 +214,18 @@ virHashGrow(virHashTablePtr table, int size) } table->size = size; - /* If the two loops are merged, there would be situations where - * a new entry needs to allocated and data copied into it from - * the main table.

[libvirt] [PATCH 0/4] Unify error messages

29 Apr '11

As libvirt error codes evolved over time, it was more unclear to know, which code should be use in what cases. This patch series tries to correct those places, so we don't say it is internal error, when in fact incorrect XML was given. Also some error messages were changed to give more hints.

[libvirt] [PATCH V3] xen: check if device is assigned to guest before reattaching
by Yufang Zhang 29 Apr '11

29 Apr '11

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=664059 This is the version3 patch for BZ#664059. Reattaching pci device back to host without destroying guest or detaching device from guest would cause host to crash. This patch adds a check before doing device reattach. If the device is being assigned to guest, libvirt refuses to reattach device to host. The patch only works for Xen, for it just checks xenstore to get pci device information. This version fixes some formatting problem and moves lock-unlock out of loop so that the check is atomic.

[libvirt] [PATCHv12 1/3] libvirt/qemu - support persistent modification of devices
by KAMEZAWA Hiroyuki 28 Apr '11

28 Apr '11

Rebased ont the latest git tree, which makes this work easier. This series adds support for attach/detach/update disks of domain config. == This patch adds functions for modify domain's persistent definition. To do error recovery in easy way, we use a copy of vmdef and update it. The whole sequence will be: make a copy of domain definition. if (flags & MODIFY_CONFIG) update copied domain definition if (flags & MODIF_LIVE) do hotplug. if (no error) save copied one to the file and update cached definition. else discard copied definition. This patch is mixuture of Eric Blake's work and mine.

[libvirt] [PATCH] Xen: Do not generate net ifname if domain is inactive
by Jim Fehlig 28 Apr '11

The xend driver will generate a virDomainNetDef ifname if one is not specified in xend sexpr, even if domain is inactive. The result is network interface XML containing 'vif-1.Y' on dev attribute of target element, e.g. <interface type='bridge'> <target dev='vif-1.0'/> ...

[libvirt] [PATCH v2 0/5] Add TXT record and hosts support for DNS service and dnsmasq command-line regression testing
by Michal Novotny 28 Apr '11

28 Apr '11

Hi, this is the patch to introduce the TXT record and DNS hosts support for the DNS service on the virtual network. This can be defined using the txt-record subelement in the dns element of the network XML description. The definition of TXT record names containing spaces is rejected with the error message that TXT record names in DNS doesn't support spaces. Also, regression testing for the dnsmasq command line has been added to test whether the dnsmasq command-line is correct or not. The new XML definition syntax is: <dns> <txt-record name="example" value="example value" /> <host ip='192.168.122.1'> <hostname>gateway</hostname> <hostname>host</hostname> </host> </dns> Where multiple host elements can be defined to put the aliases for specified IP addresses. The patch series has been tested for the configuration and it was working fine and also RelaxNG schema with the tests have been both altered to add test cases to test those patches. All of the patches passed the make, make check and make syntax-check commands and it has been tested for the definition described above and it was working fine (tested using dig for DNS TXT record and nslookup in the guest for the DNS hosts).

Hello, I just noticed strange problem. While trying to start vm with cdrom image on a samba mount, I get: libvir: Security Labeling error : unable to set user and group to '0:0' on '/home/cluster/images/interinformatics/CentOS-5.4-i386-bin-DVD.iso': Permission denied I googled this up, and found some solutions, but none seems to be suitable for me. The biggest problem is I'm not using selinux at all, its completely disabled, and I don't have a chance to change mount parameters as well... Is there any way to workaround this? thanks a lot in advance! BR nik -- ------------------------------------- Ing.

[libvirt] RFC: virt-xml: command line tool for altering guest configuration
by Cole Robinson 28 Apr '11

28 Apr '11

Hi all, Attached is a patch to virtinst.git that provides a new tool named virt-xml. virt-xml provides a scriptable command line interface for editing libvirt guest XML. A couple examples: Change boot order and boot menu for 'myguest': $ ./virt-xml --guest myguest --boot network,hd,cdrom,menu=on Requested changes: --- Original XML +++ New XML @@ -10,6 +10,8 @@ <os> <type arch="i686">hvm</type> <loader>/usr/lib/xen/boot/hvmloader</loader> + <boot dev="network"/> + <bootmenu enable="yes"/> <boot dev="hd"/> + <boot dev="cdrom"/> </os> <features> <acpi/> Change disk #7 to use cache=none for 'myguest': $ ./virt-xml --guest myguest --device 7 --disk cache=none Requested changes: --- Original XML +++ New XML @@ -74,6 +74,7 @@ <disk type="file" device="disk"> <source file="/tmp/foobar3"/> <target dev="sdd" bus="usb"/> + <driver cache="none"/> </disk> <disk type="file" device="disk"> <driver name="tap" type="qcow" cache="writethrough"/> Change watchdog action for 'myguest': $ ./virt-xml --guest myguest --device 1 --watchdog action=pause Requested changes: --- Original XML +++ New XML @@ -220,7 +220,7 @@ <address domain="0x0003" bus="0x00" slot="0x19" function="0x0"/> </source> </hostdev> - <watchdog model="ib700" action="poweroff"/> + <watchdog model="ib700" action="pause"/> <memballoon model="xen"/> </devices> </domain> --boot, --disk, and --watchdog come straight from virt-install, see man virt-install for detailed docs of the option format. Those options shown are the only things wired up right now, but it's a straightforward task to wire up most of the relevant remaining virt-install opts. Also the tool doesn't actually apply the changes yet, but that is also a trivial addition. I think the interesting bit here is nailing down the scope of the tool and deciding on good CLI syntax. Not sure if we should do hotplug/hotunplug as a subcommand or just another option like: virt-xml ... --hotplug --disk /tmp/foo.img Also not really sure how to hotunplug using the --device syntax of the above examples: virt-xml ... --hotunplug --device 1 --disk <what goes here?> We could make --device just an option to whatever device string the user gives virt-xml ... --hotunplug --disk id=1 We can easily allow different XML input methods like: virt-xml --guestxml file.xml ... or even batch processing virt-xml --guest * ... Maybe even have allow more intelligence about what guests we edit, say we want to set cache=none for all disk devices, not CDROM or floppy (this would take a bit of work to sort out). virt-xml --guest * --disk match,device=disk --disk cache=none Then there is also the question of extending the tool to also edit other XML like storage, network, interface, etc. Any recommendations appreciated: option syntax, future capabilities, or even a better name for the tool :) A quick word about why I think we should do this with a separate tool rather than virsh. For starters, I think the need for this functionality on the command line is clear by now, so it's just a question of where to implement it. Why not virsh? Text and command line processing in C is a serious pain compared to a higher level language like python. I don't think this is a controversial statement, in fact I think it's partly responsible for why the virsh XML building commands have typically been in a pretty sorry state. virsh could conceivably use the internal domain_conf API to make this task much easier, but it would still require a lot of command line options for every XML parameter. In contrast, virt-install already needs to do most of this command line processing, and virt-manager needs to do all the XML building, parsing, and editing. Since this code already lives in one place (virtinst), it's almost trivial for us to reuse it. Supporting a new XML property on the command line is a very simple task and will immediately benefit both virt-install and virt-xml. We also already have over 75% of the domain XML schema available via existing CLI options that are already documented :) Questions or comments appreciated! Thanks, Cole

[libvirt] RFC: disconnecting guest/domain interface config from host config (aka migration with macvtap)
by Laine Stump 28 Apr '11

28 Apr '11

Abstraction of guest <--> host network connection in libvirt ===================================== The <interface> element of a guest's domain config in libvirt has a <source> element that describes what resources on a host will be used to connect the guest's network interface to the rest of the world. This is very flexible, allowing several different types of connection (virtual network, host bridge, direct macvtap connection to physical interface, qemu usermode, user-defined via an external script), but currently has the problem that unnecessary details of the host config are embedded into the guest's config; if the guest is migrated to a different host, and that host has a different hardware or network config (or possibly the same hardware, but that hardware is currently in use by a different guest), the migration will fail. I am proposing a change to libvirt's network XML that will allow us to (optionally - old configs will remain valid) remove the host details from the guest's domain XML (which can move around from host to host) and place them in the network XML (which remains with the host); the domain XML will then use existing config elements to associate each guest interface with a "network". The motivating use case for this change is the "direct" connection type (which uses macvtap for vepa and vnlink connections directly between a guest and a physical interface, rather than through a bridge), but it is applicable for all types of connection. (Another hopeful side effect of this change will be to make libvirt's network connection model easier to realize on non-Linux hypervisors (eg, VMWare ESX), so Mathias - please chime in!) Background -------------------- libvirt currently has 3 major types of guest interface connection (there are also "type='user'" and "type='ethernet'", but they probably wouldn't be used in a multi-host environment, so I'm not considering them here): 1) type='network' The guest's network interface is connected to a libvirt-created "virtual network", which is in reality (in the case of KVM or Xen) a Linux bridge device that isn't connected to any physical host interface - any connection to the outside goes through the host's IP routing stack. The network to use is indicated in the <source> element of the guest's interface xml: <source network='mynetwork'/>. Because the name 'mynetwork' is controlled by libvirt, it's perfectly reasonable to assume that the same network name could be available on another host that is accepting a migrated guest. 2) type='bridge' The guest's network interface is connected to a bridge device (eg "br0") that has already been configured in the host's network config files (eg, in /etc/sysconfig/network-scripts). This bridge is itself connected to the outside via a physical host interface, eg "eth0", *NOT* through the hosts IP routing stack. The bridge to use is indicated in the source with <source bridge='br0'/>. Although the naming of the bridge is outside the scope of libvirt, it is at least possible to setup all hosts to have the same bridge name (so that a guest could be migrated from one host to another). 3) type='direct' The guest's network interface is connected directly to a physical interface (eg "eth0") with macvtap, or sometimes to a virtual function ("VF") of a physical interface (which is also really just another interface, from the software point of view). The interface to use is indicated with <source interface='eth0' mode='something'/> In this case, the interface name is determined by the host OS and cannot be arbitrarily changed. Also a host will have multiple interfaces / VFs available to guests, and in some modes may allow only a single guest to connect to a given interface (implying that the interface used by a guest when on one host will probably not be available when migrating to another). So in order to have flexible migration from one host to another, an abstraction to allow the guest XML to use the same name on all hosts must be introduced. Three possible methods for providing this abstraction come to mind: Option 1 ----------- (Be forewarned that Option 1 & 2 are shown here mainly to illustrate my thought process while arriving at my preferred Option - 3 :-) In a manner similar to the way the vnet%d tap devices are created, name the interface with an embedded variable (eg "eth%d") (plus attributes for min and max %d) and let the underlying code in libvirt search for/reserve an appropriate device> This is the simplest to code/configure, but does not allow a) more complex names (eg, interface names as determined by biosdevname can be of the form "pci%dp%d_%d"), b) multiple ranges, c) oversubscribing of interfaces (it is possible, although sub-optimal, to connect multiple guest interfaces to a single host interface with macvtap). VERDICT: looks ugly, not flexible enough. Option 2 ----------- create a new class of libvirt XML config to describe a pool of network interfaces, and reference this pool in the guest interface element: <interface type='interfacePool'> <source pool='red-network'/> ... </interface> The problem with this is that it requires a new API for defining/undefining/etc management of "interface pools". Also, it wouldn't allow (for example) one host to use a pool of macvtap addresses to connect guests, and another host to use a host bridge for the same connection (obviously, such a non-uniform setup wouldn't be desirable in a large host farm, but may be encountered in some smaller setup) VERDICT: creates more API clutter (ie extra work *and* confusion for users). Is "flexible enough" for current motivation, but unnecessarily limiting, eg doesn't help the model to be more easily adapted to VMWare etc. Option 3 ----------- Up to now we've only discussed the need for separating the host-specific config (<source> element) in the case of type='direct' interfaces (well, in reality I've gone back and edited this document so many times that is no longer true, but play along with me! :-). But it really is a problem for all interface types - all of the information currently in the guest's interface <source> element really is tied to the host, and shouldn't be defined in detail in the guest XML; it should instead be defined once for each host, and only referenced by some name in the guest XML; that way as a guest moves from host to host, it will automatically adjust its connection to match the new environmant. As a more general solution, instead of having the special new "interfacePool" object in the config, what if the XML for "network was expanded to mean "any type of guest network connection" (with a new "type='xxx'" attribute at the toplevel to indicate which type), not just "a private bridge optionally connected to the real world via routing/NAT"? If this was the case, the guest interface XML could always be, eg: <interface type='network'> <source network='red-network'/> ... </interface> and depending on the network config of the host the guest was migrated to, this could be either a direct (macvtap) connection via an interface allocated from a pool (the pool being defined in the definition of 'red-network'), a bridge (again, pointed to by the definition of 'red-network', or a virtual network (using the current network definition syntax). This way the same guest could be migrated not only between macvtap-enabled hosts, but from there to a host using a bridge, or maybe a host in a remote location that used a virtual network with a secure tunnel to connect back to the rest of the red-network. (Part of the migration process would of course check that the destination host had a network of the proper name, and fail if it didn't; management software at a level above libvirt would probably filter a list of candidate migration destinations based on available networks, and only attempt migration to one that had the matching network available). Examples of 'red-network' for different types of connections (all of these would work with the interface XML given above):  <network>  <name>red-network</name> <bridge name='virbr0'/> <forward mode='route'/> ... </network>  <network type='bridge'> <name>red-network</name> <bridge name='br0'/> </network> <network type='direct'> <name>red-network</name> <source mode='vepa'>   </source>    </network> I know there may be some resistance to this expansion of the usage of <network>, but I think it does fit in with the current usage properly, and is preferable to adding an entire new class of API just to define a pool of interfaces. Open questions: 1) What should the <pool> element inside network/source look like. Making each interface in the pool a separate element, with possible attributed, would be the simplest to code, but would get tedious on a system with, for example, an ethernet card with 64 VFs. On the other hand, just parameterizing a string (eth%d) is inadequate, eg, when there are multiple non-contiguous ranges. 2) do we need a "max connections" for each interface in a pool of macvtap interfaces? Or should we just overload them in a round-robin fashion unless mode='passthru' (a new mode which requires only one guest per interface). 3) What about the parameters in the <virtualport> element that are currently used by vepa/vnlink. Do those belong with the host, or with the guest? 4) Are there other <network> types that we want? Perhaps the recent proposal for IPSec / secure tunnels could be incorporated as a new network type (or maybe it could just be the standard "virtual" type, with a tunnel as the forward device).

[libvirt] [PATCH] fix virsh's regression
by Wen Congyang 28 Apr '11

28 Apr '11

This patch does the following things: 1. The return value of cmdSchedInfoUpdate() can be -1, 0 and 1. So the type of return value should be int not bool.(This function is not a entry of a virsh command, but the name of this function likes cmdXXX) 2. The type of cmdSchedinfo()'s, cmdFreecell()'s, cmdPoolList()'s and cmdVolList()'s return value is bool not int, so change the type of variable ret_val, func_ret and functionReturn. 3. Add a variable functionReturn for cmdMigrate(), cmdAttachInterface(), cmdDetachInterface(), cmdAttachDisk() and cmdDetachDisk() to save the return value. 4. Change the type of variable ret in the function cmdAttachDevice(), cmdDetachDevice(), cmdUpdateDevice(), cmdAttachInterface(), cmdDetachInterface(), cmdAttachDisk() and cmdDetachDisk() to int, as we use it to save the return value of virXXX() and the type of virXXX()'s return value is int not bool. 5. Do some cleanup when virBuff.error is 1.

[libvirt] [PATCH V2] xen: check if device is assigned to guest before reattaching
by Yufang Zhang 27 Apr '11

27 Apr '11

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=664059 This is the version2 patch for BZ#664059. Reattaching pci device back to host without destroying guest or detaching device from guest would cause host to crash. This patch adds a check before doing device reattach. If the device is being assigned to guest, libvirt refuses to reattach device to host. The patch only works for Xen, for it just checks xenstore to get pci device information.

[libvirt] [PATCH] qemu: Add option to enable/disable IOEventFD feature

This feature allows QEMU to achieve higher throughput, but is available only in recent versions. It is accessible via ioeventfd attribute with accepting values 'on', 'off'. Only experienced users needs to set this, because QEMU defaults to 'on', meaning higher performance.

[libvirt] [PATCH] esx: Fix dynamic dispatch for CastFromAnyType functions
by Matthias Bolte 27 Apr '11

27 Apr '11

This was broken by the refactoring in ac1e6586ec75. It resulted in a segfault for 'virsh vol-dumpxml' and related volume functions. Before the refactoring all users of the ESX_VI__TEMPLATE__DISPATCH macro dispatched on the item type, as the item is the input to all those functions. Commit ac1e6586ec75 made the dynamically dispatched CastFromAnyType functions use this macro too, but this functions dispatched on the actual type of the AnyType object. The item is the output of the CastFromAnyType functions. This difference was missed in the refactoring, making CastFromAnyType functions dereferencing the item pointer that is NULL at the time of the dispatch. --- src/esx/esx_vi_types.c | 12 ++++++------ 1 files changed, 6 insertions(+), 6 deletions(-) diff --git a/src/esx/esx_vi_types.c b/src/esx/esx_vi_types.c index dd83954..6a2d5cf 100644 --- a/src/esx/esx_vi_types.c +++ b/src/esx/esx_vi_types.c @@ -533,8 +533,8 @@ * Macros to implement dynamic dispatched functions */ -#define ESX_VI__TEMPLATE__DISPATCH(__type, _dispatch, _error_return) \ - switch (item->_type) { \ +#define ESX_VI__TEMPLATE__DISPATCH(_object, __type, _dispatch, _error_return) \ + switch ((_object)->_type) { \ _dispatch \ \ case esxVI_Type_##__type: \ @@ -543,7 +543,7 @@ default: \ ESX_VI_ERROR(VIR_ERR_INTERNAL_ERROR, \ _("Call to %s for unexpected type '%s'"), __FUNCTION__, \ - esxVI_Type_ToString(item->_type)); \ + esxVI_Type_ToString((_object)->_type)); \ return _error_return; \ } @@ -585,7 +585,7 @@ #define ESX_VI__TEMPLATE__DYNAMIC_FREE(__type, _dispatch, _body) \ ESX_VI__TEMPLATE__FREE(__type, \ - ESX_VI__TEMPLATE__DISPATCH(__type, _dispatch, /* nothing */) \ + ESX_VI__TEMPLATE__DISPATCH(item, __type, _dispatch, /* nothing */) \ _body) @@ -618,14 +618,14 @@ #define ESX_VI__TEMPLATE__DYNAMIC_CAST_FROM_ANY_TYPE(__type, _dispatch) \ ESX_VI__TEMPLATE__CAST_FROM_ANY_TYPE_EXTRA(__type, esxVI_##__type, \ - ESX_VI__TEMPLATE__DISPATCH(__type, _dispatch, -1), \ + ESX_VI__TEMPLATE__DISPATCH(anyType, __type, _dispatch, -1), \ /* nothing */) #define ESX_VI__TEMPLATE__DYNAMIC_SERIALIZE(__type, _dispatch, _serialize) \ ESX_VI__TEMPLATE__SERIALIZE_EXTRA(__type, \ - ESX_VI__TEMPLATE__DISPATCH(__type, _dispatch, -1), \ + ESX_VI__TEMPLATE__DISPATCH(item, __type, _dispatch, -1), \ _serialize) -- 1.7.0.4

[libvirt] Entering devel freeze tomorrow
by Daniel Veillard 27 Apr '11

27 Apr '11

Well I initially suggested to enter freeze the last week-end but I had a serious backlog and let a few day pass. What I suggest is enter freeze tomorrow morning (my time, i.e. very early) at which point I will make a first candidate release tarball for testing. Then the target for the actually release might be Wed 4 or Thu 5 depending on how things turns out. If there is patches for new features that people want in but didn't get the ACK, please raise them again quickly today so we can try to review them and push in time for 0.9.1, otherwise, that will be 0.9.2 in a month, thanks !

[libvirt] libvirt and redis
by B Gordon 26 Apr '11

26 Apr '11

Is there interest in teaching libvirt to store configs in a DB? I'd like to talk out what's desirable in the scope and design with someone who knows libvirt. My eventual goal is to synchronize config between multiple libvirtds using Redis. I've been playing with a prototype that abstracts config writing and reading into handlers that can be selected at run time or from libvirtd.conf. This was to get me some familiarity--please tell me what aspects I should change to suit the rest of libvirt. The high-level, emphasizing the more questionable aspects: * "conf drivers" that cargo-cult the jargon used in "drivers" a bit even though they (currently) aren't quite a fit with the way current ones are used. * One global conf driver, because it needs to be accessed in other state drivers when a connection is not currently present in the API. * conf drivers present a file system-like key/value API to the rest of libvirt to minimize disruption. They receive an XML string to store and must be able to list the keys in a given "directory". Retrieval is done by passing an optional callback to xml.c that it will use instead of xmlCtxtReadFile(). * Keys should probably not include the full sysconfdir path, and many other ways the prototype is too FS-like. * With a relational DB, API calls to store each type of libvirt struct might make more sense than formatted XML strings. I have not tried to do this and vaguely hope that working with XML in a relational DB would be acceptable or that those calls could be added later. Using the DB's native XML handling might better for abstraction, actually. * The conf driver needs a way to receive parameters from libvirtd.conf. URI parsing? Some other key-value format?

[libvirt] [PATCH] Fix disability to run on systems with no PCI bus
by Michal Privoznik 22 Apr '11

22 Apr '11

The patch which moved libpciaccess initialization to one place caused regression - we were not able to run on system with no PCI bus, like s390(x).

New code should use just 'qemu'. Yes, I know that changing it now means more merge conflicts to resolve later in the series.

I undid it. ACK with those nits fixed, so I pushed a modified version (shoot; I've lost an easy way to have git show my incremental diffs, due to the merge conflict resolution from the renames). -- Eric Blake eblake(a)redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
