[libvirt] qemudDomainSetMemory() / qemudDomainSetVcpus() error codes
by Kaitlin Rupert 11 Jun '08

11 Jun '08

Hello, I noticed qemudDomainSetMemory() / qemudDomainSetVcpus() use the VIR_ERR_INTERNAL_ERROR error code when the caller attempts to set the mem/vcpus of an active domain. In this case, returning something like VIR_ERR_NO_SUPPORT would indicate that this is an invalid call - which would distinguish the error from a failure that occurred during the call. Is it possible to use such a return code to indicate what is supported by QEMU/KVM and what isn't? Thanks! -- Kaitlin Rupert IBM Linux Technology Center kaitlin(a)linux.vnet.ibm.com

[libvirt] Release?
by Richard W.M. Jones 10 Jun '08

10 Jun '08

I've just had a chat with Daniel about whether it's time for a new release of libvirt. My own primary focus is getting the virDomain*Peek APIs into a released version so I can use them from Fedora. libvirt 0.4.2 was released on 8th Apr 2008. I just scanned the changelog and there's a pretty long list of new features: - Support for serial and parallel devices in Xend - Network interface model in QEMU network devs - SetVcpus, DomainGetMaxVcpus, VCPU pinning in QEMU - Disk "bus"es - Support for Xenner - Deprecate conn/dom/net fields in virterror - HTML documentation completely restructured - MinGW fixes - Memory leaks plugged - Added HACKING file and lots of work on unifying syntax and methods used in the code base to a single standard - Lots of LXR changes - virDomain*Peek APIs - and of course many bug fixes So is it time for a release?

[libvirt] [PATCH] Fix UUIDString for python bindings
by Cole Robinson 10 Jun '08

10 Jun '08

The attached patch fixes a few issues in the python bindings. First, UUIDString has, to my understanding, never worked. It expected to be passed a buffer to fill with the uuid, which through my tests isn't realistically doable from python. I added custom bindings to fix this, and it now works as expected, taking no arguments and returning a string. UUID for a storage pool wasn't being generated with its custom function, so it too was broken. This is also fixed. I also removed some stale entries for virStorageVol UUID functions from generator.py which were probably just carried along from an old version of the storage api patches (storage volumes don't use UUID).

[libvirt] [PATCH] virDomainMemoryPeek - peek into guest memory

This patch implements virDomainMemoryPeek, which allows callers to peek into guest (virtual) memory. Currently the patch contains a QEMU driver and remote support. There's also a big comment in the source describing how to do Xen. Obviously the use case for this is virt-mem: http://et.redhat.com/~rjones/virt-mem/ Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones Read my OCaml programming blog: http://camltastic.blogspot.com/ Fedora now supports 59 OCaml packages (the OPEN alternative to F#) http://cocan.org/getting_started_with_ocaml_on_red_hat_and_fedora

[libvirt] [PATCH] lxc: new tty for container
by Dave Leskovec 10 Jun '08

10 Jun '08

The lxc driver xml parser treats the console element as input when it should be output only. This obviously causes problems when anything other than /dev/ptmx is specified or when a container is shutdown and then restarted without redefining it (so that the console field is reset). This patch treats the console element as output only and always creates a new device when starting a container. Also fixed up a string overflow when storing the device name.

[Libvir] Reopening the old discussion about virDomainBlockPeek
by Richard W.M. Jones 09 Jun '08

09 Jun '08

Virt-df[1] has now gained the ability to fully parse LVM2 partitions, thus: # virt-df -c qemu:///system -h Filesystem Size Used Available Type rhel51x32kvm:hda1 96.8 MiB 14.6 MiB 82.2 MiB Linux ext2/3 rhel51x32kvm:VolGroup00/LogVol00 6.4 GiB 3.6 GiB 2.8 GiB Linux ext2/3 rhel51x32kvm:VolGroup00/LogVol01 992.0 MiB Linux swap However it still has to do it by opening the local partitions / files, which means it isn't using a "proper" part of libvirt and more importantly it cannot run remotely. I'd like to find out whether the time has come for us to look again at a virDomainBlockPeek call for libvirt. Here is the original thread plus patch from 7 months ago: http://www.redhat.com/archives/libvir-list/2007-October/thread.html#00089 (I've attached an updated patch against current CVS). I appreciate that some cases might not be simple (iSCSI?), but the same argument applies to block device statistics too, and we make those available where possible. I think a best-effort call allowing callers to peek into the block devices of guests would be very useful. Rich.

[libvirt] Workshop Virtualization Technologies in Essen, Germany
by Henning Sprang 04 Jun '08

04 Jun '08

Hello everybody! For the third time, I arranged a "Workshop on Virtualization Technologies" in cooperation with the Linuxhotel in Essen, Germany. Our goal is, to provide developers of Open Source Software related to virtualization, and interested, skilled administrators with the possibility to come together for a weekend to work on their projects, exchange experiences and play around with the technology. The Linuxhotel as a location delivers a great, relaxed athmosphere and a perfect infrastructure to enable carefree working. Details - currently in German only - here: https://wiki.villa-vogelsang.de/doku.php?id=virtualisierung:start It's no problems to attend the workshop if you're not speaking german - please let me know if you're interested, and I'll give you more info on the details - basically it is, if you are an OpenSource developer in a virtualization related field, you can attend for free, otherwise you have to pay a flat fee of 135 Euros. We're looking for sponsors to see if we can get to reimburse travel costs for the Open Source developers. I'd be glad to see you there! Registration will be by first come-first serve principle - the event will be limited to 20 Persons. Henning Sprang -- Henning Sprang http://www.sprang.de | http://lazyb0y.blogspot.com/

[libvirt] remote access libvirtd / bindings for php/asp
by Stefan de Konink 04 Jun '08

04 Jun '08

Hi, A few people around me want to use php or asp to access libvirtd. Along this wish is to access it as 'proxy' for the entire cluster (this is where I come in). My target it to make a proxy for libvirtd that allows all host in the network to be managed by any libvirtd instance that has the sufficient certificate. Now it seems clear that this dispatch/proxy functions are doable. But what I wonder about is the actual access to libvirtd. There seems to be a pretty big warning about the XDR/ RPC calls. My people would like to see bindings to connect to libvirtd by php or asp/.net, is there any progress on that one? Stefan

[libvirt] ANNOUNCE: virt-mem: tools for monitoring virtual machines
by Richard W.M. Jones 04 Jun '08

04 Jun '08

I'm pleased to announce this very early pre-alpha release of a further set of tools for monitoring virtual machines. The idea is to provide simple commands which can be run outside the virtual machine to monitor its status. These commands don't require you to log in to the virtual machine, or to install any software, since they work entirely by snooping. So they could be very useful for analyzing guests which are stuck / unresponsive / heavily loaded. Done so far: virt-uname like uname(1), print guest's system information virt-dmesg like dmesg(1), print guest's kernel messages Coming soon: virt-ps like ps(1), lists processes virt-free like free(1), lists free memory and swap If virt-ps works out, I might do a 'top'-like command, although of course I can't call it virt-top. I'm open to other suggestions too.

[libvirt] [PATCH] kvm 32bit guest on 64bit host
by Gerd von Egidy 03 Jun '08

03 Jun '08

Hi, I want to manage a 32 bit i686 guest on an x86_64 host with kvm and libvirt. KVM is perfectly capable of doing this (look e.g. at http://kvm.qumranet.com/kvmwiki/Guest_Support_Status) but libvirt did not allow it. So I created the attached patch to allow it and make it easy to extend the capabilities of kvm and kqemu later on. I did not add anything I'm not sure about, so I did not at 64bit guest on 32bit host (though the page linked above seems to indicate that it works) and did not change the capabilities of kqemu at all (because I don't have any experience with it and never used it). Please consider merging. Kind regards, Gerd -- Address (better: trap) for people I really don't want to get mail from: james(a)cactusamerica.com

[libvirt] Support for passing arbitrary qemu/kvm admin console commands?
by Charles Duffy 03 Jun '08

03 Jun '08

I'm looking at building a framework which makes use of KVM's pseudo-migration support for snapshot management. To my knowledge, this functionality is not presently available through libvirt. Is it possible to send arbitrary qemu/kvm admin console commands to a VM started and controlled by libvirt, or does any requirement for funtionality not presently exposed through libvirt conflict with its use? Thanks!

[libvirt] [PATCH] Add error message when the invalid XML file is defined.
by Hiroyuki Kaguchi 03 Jun '08

03 Jun '08

Hi, When cpuset that is the attribute of vcpu tag of the XML file is the invalid string, "virsh define" succeeds. (Ex. <vcpu cpuset='aaa'>4</vcpu> <vcpu cpuset=' '>4</vcpu> <vcpu cpuset=',,,'>4</vcpu> ) The patch changes policy that the definition is failed and shows error message.

[libvirt] network unreachable on XEN guest
by Kenneth Nagin 03 Jun '08

03 Jun '08

I created a new network based on the default network. However the network is unreachable to the XEN guest. I used net-dumpxml to print the "default" xml. I changed the network XML network name, bridge name, and uuid and successfully created a new network. I replaced source network attribute in the domain creation XML to point to the new network name. However, the guest can not properly initialize eth0 because the new network is unreachable. It tries to ping the ip assigned to the new bridge but fails. The same guest created with the default network works fine, i.e. it can access the network. This what network restart looks like on the guest (I'm not sure if this will be visible on the forum): (Embedded image moved to file: pic26442.jpg) This is a copy of the network XML: <network> <name>test-net1</name> <uuid>7cfbfa88-542f-44c7-bbc1-3e19f67d8ca6</uuid> <forward mode='nat'/> <bridge name='test-br1' stp='on' forwardDelay='0' /> <ip address='192.168.122.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.122.2' end='192.168.122.254' /> </dhcp> </ip> </network> This the interface segment domain creation XML: <interface type='network'>  <source network='test-net1'/> <script path='vif-bridge'/> </interface> This is the relevant ifconfig on host: .... test-br1 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:81 errors:0 dropped:0 overruns:0 frame:0 TX packets:28 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:9768 (9.5 KiB) TX bytes:5018 (4.9 KiB) vif13.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:90 errors:0 dropped:0 overruns:0 frame:0 TX packets:194 errors:0 dropped:2771 overruns:0 carrier:0 collisions:0 txqueuelen:32 RX bytes:11136 (10.8 KiB) TX bytes:10122 (9.8 KiB) virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:365 errors:0 dropped:0 overruns:0 frame:0 TX packets:3291 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:34127 (33.3 KiB) TX bytes:512877 (500.8 KiB) This the brctl show output: bridge name bridge id STP enabled interfaces br1 8000.000000000000 no eth1 8000.001a64a12e56 no peth1 test-br1 8000.feffffffffff yes vif13.0 virbr0 8000.000000000000 yes What am I missing?

[libvirt] PATCH: Switch remote daemon to use memory alloc APIs

[libvirt] [PATCH 4/4] lxc: store tty pid
by Dave Leskovec 31 May '08

31 May '08

This patch will use a file in the lxc configuration directory to store the tty forwarding process pid. The pid is stored after the process is fork()'d. It's loaded during startup when the config for a running container is loaded. The file is deleted when the domain is undefined. This should avoid "losing" the tty pid over a libvirtd restart. -- Best Regards, Dave Leskovec IBM Linux Technology Center Open Virtualization

[libvirt] [PATCH 2/4] lxc: ignore ECHILD errors during vm cleanup
by Dave Leskovec 30 May '08

[libvirt] [PATCH 1/4] lxc: validate tty pid before kill()
by Dave Leskovec 30 May '08

30 May '08

This patch adds a check of the tty forwarding process pid before kill()'ing it when destroying a domain. If the pid value stored in the the vm structure is invalid, sending a SIGKILL may be very bad if the value in question is something like -1 (which just happens to be it's initial value). -- Best Regards, Dave Leskovec IBM Linux Technology Center Open Virtualization

This set of patches fixes a few items that occur as a result of a restart of libvirtd when containers are running. While this may not be a common situation, the consequences of some of these (particularly losing the tty forwarding process pid and later trying to kill it) can be quite severe. -- Best Regards, Dave Leskovec IBM Linux Technology Center Open Virtualization

The latter was auto-generating incorrectly, so this patch overrides its API contract making the generator work correctly. Dan.

[libvirt] PATCH: Convert lots of code to new memory APIs
by Daniel P. Berrange 28 May '08

28 May '08

This patch converts a large amount of the XML parsing/generating code in the Xen and QEMU drivers over to using the new memory APIs, so we can get OOM checking of it.

[libvirt] PATCH: Convert buf.c to use memory alloc wrappers
by Daniel P. Berrange 28 May '08

28 May '08

This patch coverts the virBuffer code over to using our internal memory allocation wrappers.

[libvirt] PATCH [0/2]: Deprecate conn, dom, net virterror fields
by Richard W.M. Jones 28 May '08

28 May '08

This is a pair of patches which deprecate the conn, dom and net fields in the virterror structure. Programs which use these fields will get a warning (if compiled under gcc anyway): foo.c:123: warning: 'dom' is deprecated (declared at /usr/include/libvirt/virterror.h:81) The fields themselves are still present and still set, so the ABI isn't changed. Now the patch is quite a lot more involved than you might think for such a simple change. Part of the problem is that we want to allow libvirt itself to modify these fields without generating a warning. Therefore the first part of the patch has to refactor all code within libvirt which includes "libvirt.h" or "virterror.h" (the public headers) so that instead this code just includes "internal.h". "internal.h" already includes the public headers. This allows "internal.h" to undefine the deprecation macro. Of course nothing is quite so simple. We have two "internal.h" files, so I renamed the one in the qemud directory to "qemud.h". I also added something in the HACKING file, stating how *.c files within libvirt should include header files. The second part of the patch actually adds the deprecation to the fields in virterror, and hence is small and simple.

[libvirt] PATCH: 0/4: Add out-of-memory validation to the testsuite
by Daniel P. Berrange 28 May '08

28 May '08

The following series of patches add infrastructure neccessary to let us test OOM handling for any libvirt code using our malloc wrappers. Currently only a few places use this, but as this series will show, it already lets us find several bugs. As we convert more code away from malloc to VIR_MALLOC we'll get ever improved coverage. Not testing with malloc() directly also means we avoid having to debug code in libraries we link to. Although obviously it'd be nice if they had correct OOM handling, that's their job to debug not ours...

[libvirt] How to add a new Hypervisor support
by Amudhan Gunasekaran 28 May '08

28 May '08

Hi, I am investigating libvirt to find out whether adding a hypervisor support is possible. I went through libvirt.c and found that all the operations are done through the struct virConnect. But virConnect is not exposed to public. So, if I want to add a minimum support for VMWare and Hyper-V hypervisors, is it possible? If it is possible, how should I proceed. Thanks, Amudhan.

[Libvir] ISCSI howto, example, etc?
by Mark Dehus 24 May '08

24 May '08

The documentation on the new storage feature is either a little short, or I totally missed it. Anyway, I am looking for some help on how to use it. If anyone could maybe give me an example xml file that would be incredibly helpful, because based on the format description I can't exactly figure out what information I am supposed to put where (for ISCSI). Thanks! -- $ ./Mark

[libvirt] Switch to using lcov for test coverage reports
by Daniel P. Berrange 23 May '08

23 May '08

I got fed up trying to figure out how to fix the coverage reports to merge data from multiple runs correctly, so this patch rips out all our test coverage support. In its place is a makefile rule which just calls out to the lcov program. It requires lcov >= 1.6 since earlier versions were too dumb to deal with .libs/ directories properly. This version has just been submitted to Fedora updates repos.

[libvirt] PATCH: Fix a small bug in rpcgen_fix.pl script
by Richard W.M. Jones 23 May '08

23 May '08

There's a warning about type-punning in CVS libvirt. We normally rewrite the code generated by glibc rpcgen to avoid these warnings, but because the variable in question has a name containing an uppercase letter, and because the regexp we're using is case-sensitive and only matches lowercase identifiers, the rewrite wasn't happening. Attached patch fixes this. Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-top is 'top' for virtual machines.

[libvirt] PATCH: Misc fixes to qparams
by Daniel P. Berrange 23 May '08

23 May '08

I found a couple more small bugs in the qparams code - In the qparam_query_parse() method, after appending each (name,value) pair of params, it failed to free the temporary buffers for the (name,value) pair. - Did not allow for ';' as a valid query parameter separator - In a couple of OOM cleanup scenarios it failed to free buffers allocated earlier on In looking at this I decide we ought to have a test suite for this code so I'm also including one. It has 100% coverage of all the non-OOM code paths.
