[Libvir] [RFC] 0/3 Add Linux Container support to libvirt
by Dave Leskovec 21 Feb '08

21 Feb '08

The following set of patches add the first batch of linux container support to libvirt. The work is not complete but I wanted to start getting some of this out for comments. This set of patches supports the following: * new switch --with-lxc to enable linux container support (off by default) * virConnectOpen * virConnectClose * virConnectListDomains (of course none are listed since we can't start the containers yet) * virConnectNumOfDomains * virConnectListDefinedDomains * virConnectNumOfDefinedDomains * virDomainLookupByUUID * virDomainLookupByName * virDomainGetInfo * virDomainGetXMLDesc * virDomainDefineXML * virDomainUndefine A sample XML format that can be used to define a linux container domain: <domain type='linuxcontainer'> <name>TestContainer3</name> <container> <filesystem type='mount'> <source dir='/home/user/lxc_files/etc/'/> <target dir='/etc/'/> </filesystem> <filesystem type='mount'> <source dir='/home/user/lxc_files/var/'/> <target dir='/var/'/> </filesystem> <init>/usr/sbin/container_init</init> </container> <memory>65536</memory> <devices> <console tty='/dev/pts/4'/> </devices> </domain> I've left out the network definition as I'll be tackling that a little later on... I'm currently working on starting a container. Any and all questions and comments are welcome. Thanks! -- Best Regards, Dave Leskovec IBM Linux Technology Center Open Virtualization

[Libvir] [PATCH] Rewrite openvzSetUUID.
by Jim Meyering 21 Feb '08

21 Feb '08

There were several unchecked syscalls in this function, along with the at-least-theoretical risk of a file descriptor leak, so I rewrote this function to avoid all that, using a stream rather than a bare file descriptor. Subject: [PATCH] Rewrite openvzSetUUID. * src/openvz_conf.c (openvzSetUUID): Rewrite to avoid unchecked lseek, write, and close as well as a potential file descriptor leak. Regarding style, the if (expr1 + expr2 + expr3) below might look odd, but it's better than "if (expr1 || expr2 || expr3)", which loses if expr1 or expr2 is true, since it short-circuits and skips expr3, which is the required fclose call. I could have used "|", but that seemed worse, and I didn't like the duplication in if (expr1) ret = -1; if (expr2) ret = -1; if (expr3) ret = -1; In an early iteration, I even wrote this (which still has too much duplication but isn't that bad): ret = 0; ret |= e1; ret |= e2; ret |= e3; Anyway, just trying to avoid a drawn-out discussion on style....

Hi, the patch is now in attachement.. I think, that the statement if (!vm) vm = *pnext; will never be executed: in the first pass, we have already check this a few lines before; in next passes, vm remains the same... Anton

[Libvir] RFC: Updated async job public API
by Daniel P. Berrange 20 Feb '08

20 Feb '08

A little over a month ago I proposed an API extension for enabling long operations to be done as asynchronous background jobs. http://www.redhat.com/archives/libvir-list/2008-January/msg00040.html While the proof of concept definitely worked, having played around & thought about it a little more I feel we can do better than that initial proposal. Some things I didn't like about it: - Complicated reference counting. This was because jobs may or may not be tied to a virDomainPtr object depending on whether the job was a creation attempt, or an operation on an existing object. - Complicated app code because they now had to track both Job & Domain objects together. - Added too many new APIs - this was a consequence of needing the separate top level virJob object, adding lots of XXXJob variants for APIs. - Complicated internal drivers due to the separate Job object. So to try and address this I've come up with an alternative, simpler design for this. The key idea is to get rid of the top level 'Job' object and make use of the 'flags' field present in (almost) all the APIs which need to have async behaviour. First of all, for the couple of APIs which don't have 'flags' we add new variants taking a 'flags' parameter. For each API needing to allow async operation, we define a flag for this eg, virDomainCreateXML -> VIR_DOMAIN_CREATE_XML_ASYNC virDomainRestore -> VIR_DOMAIN_RESTORE_ASYNC virStoragePoolBuild -> VIR_STORAGE_POOL_BUILD_ASYNC If the flag is omitted, current semantics are unchanged, so existing apps are not impacted. If you pass the appropriate XXX_ASYNC flag, then you cannot assume that the operation is complete upon returning from the call. To check completion status you ask for the virJobInfo data. This can be done with whichever of these APIs matches: virDomainGetJobInfo(virDomainPtr dom, virJobInfoPtr job) virStoragePoolGetJobInfo(virStoragePoolPtr vol, virJobInfoPtr job) virStorageVolGetJobInfo(virStorageVolPtr vol, virJobInfoPtr job) Finally, you can cancel an operation: virDomainCancelJob(virDomainPtr dom); virStoragePoolCancelJob(virStoragePoolPtr pool); virStorageVolCancelJob(virStorageVolPtr vol); If you passed the XXX_ASYNC flag, it is forbidden to call any APIs on the object other than the XXXCancelJob() or XXXGetJobInfo() methods, until the job is complete. This was true of the previous proof of concept I did but I didn't spell it out at the time. I've not done the intenral driver impl of this proposal yet, but it will be easier/clearer than the previous impl, and the virsh changes will be much less intrusive since we're merely passing a flag instead of calling a completely separate API. The patch below illustrates the proposed public API - note how its only adding a handful of new entry points - 3 virDomain methods needed an extra flags parameter - all the storage APIs were written to take flags already Dan. diff -r 3b8d18bc4d3e include/libvirt/libvirt.h.in --- a/include/libvirt/libvirt.h.in Wed Feb 20 12:20:50 2008 -0500 +++ b/include/libvirt/libvirt.h.in Wed Feb 20 14:14:09 2008 -0500 @@ -408,6 +408,62 @@ char * virConnectGetCap unsigned long long virNodeGetFreeMemory (virConnectPtr conn); + + +/* + * Asynchronous background jobs + */ + +/** + * virJobType; + * + * A job may have a finite bounded progress, or may be + * unbounded. + */ +typedef enum { + VIR_JOB_BOUNDED = 0, /* finite, 0-> 100 completion */ + VIR_JOB_UNBOUNDED = 1, /* unknown completion percent */ +} virJobType; + + +/** + * virJobState; + * + * A job may be in one of several states + */ +typedef enum { + VIR_JOB_RUNNING = 0, /* Still active */ + VIR_JOB_COMPLETE = 1, /* Completed successfully */ + VIR_JOB_FAILED = 2, /* Failed to complete see virJobGetError */ + VIR_JOB_CANCELLED = 3, /* User requested cancellation */ +} virJobState; + +/** + * virJobInfoPtr: + * + * a virJobInfo is a structure filled by virJobGetInfo() and extracting + * runtime informations for a given active Job + */ + +typedef struct _virJobInfo virJobInfo; + +struct _virJobInfo { + int type; /* One of virJobType constants */ + int state; /* One of virJobState constants */ + unsigned int runningTime; /* Actual running time in seconds */ + unsigned int remainingTime;/* Estimated remaining time in seconds */ + int percentComplete; /* Completion progress 0 -> 100, if VIR_JOB_BOUNDED */ +}; + +/** + * virJobInfoPtr: + * + * a virJobInfoPtr is a pointer to a virJobInfo structure. + */ + +typedef virJobInfo *virJobInfoPtr; + + /* * Gather list of running domains */ @@ -447,6 +503,11 @@ int virDomainDestroy (virDomainPtr dom int virDomainDestroy (virDomainPtr domain); int virDomainFree (virDomainPtr domain); + +int virDomainGetJobInfo (virDomainPtr dom, + virJobInfoPtr info); +int virDomainCancelJob (virDomainPtr dom); + /* * Domain suspend/resume */ @@ -458,8 +519,14 @@ int virDomainResume (virDomainPtr dom */ int virDomainSave (virDomainPtr domain, const char *to); +int virDomainSaveFlags (virDomainPtr domain, + const char *to, + unsigned int flags); int virDomainRestore (virConnectPtr conn, const char *from); +int virDomainRestoreFlags (virConnectPtr conn, + const char *from, + unsigned int flags); /* * Domain core dump @@ -535,6 +602,8 @@ int virConnectListDefinedDomains (virC char **const names, int maxnames); int virDomainCreate (virDomainPtr domain); +int virDomainCreateFlags (virDomainPtr domain, + unsigned int flags); int virDomainGetAutostart (virDomainPtr domain, int *autostart); @@ -897,6 +966,11 @@ int virStoragePoolRefresh (virStorage int virStoragePoolRefresh (virStoragePoolPtr pool, unsigned int flags); +int virStoragePoolGetJobInfo (virStoragePoolPtr pool, + virJobInfoPtr info); +int virStoragePoolCancelJob (virStoragePoolPtr pool); + + /* * StoragePool information */ @@ -955,6 +1029,10 @@ char * virStorageVolGetXMLDesc (virSt char * virStorageVolGetPath (virStorageVolPtr vol); +int virStorageVolGetJobInfo (virStoragePoolPtr pool, + virJobInfoPtr info); +int virStorageVolCancelJob (virStoragePoolPtr pool); + #ifdef __cplusplus } #endif . -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|

[Libvir] PATCH: 0/16: Storage management APIs
by Daniel P. Berrange 20 Feb '08

20 Feb '08

The patch series that follows provides storage management APIs for dealing with local directories, local filesystems, remote filesystems, logical volumes (LVM), disk partitioning, and iSCSI. It will also soon support SCSI host adapters (including NPIV). I'll include comments inline with each patch. The final patch in the series also provides a 'storage.html' page for the website giving a fairly friendly overview of the storage pool types and their associated XML examples. Although included here, the one API i really don't like is the one for discovery virConnectDiscoverStoragePools, since its API is not flexible enough in terms of metadata it accepts. I will probably just leave this out next time around, since its not critical for the core functionality and can thus be added later. Also TBD is a way to format a filesystem on a volume, and how to clone an existing volume, and take a snapshot. These things can all be added at a later date. Finally it does not include the async job support. This is also best added once the core code is merged.

[Libvir] Dependent Xen and Libvirt patches?
by Ryan Scott 16 Feb '08

16 Feb '08

Hi all, I have a question about compatibility issues when submitting changes to both Xen and libvirt. First, some background: I'm seeing a problem with virsh detach-disk. It'll detach a disk from a running domain, but not update the domain's configuration, so the disk will be back when the domain is rebooted. This seems undesirable; I think the disk should be permanently removed by virsh detach-disk. To fix this, patches are necessary in both Xen and Libvirt. First, the Xen patch: --- old/tools/python/xen/xend/server/SrvDomain.py +++ new/tools/python/xen/xend/server/SrvDomain.py @@ -186,7 +186,9 @@ def op_device_destroy(self, _, req): return self.call(self.dom.destroyDevice, [['type', 'str'], - ['dev', 'str']], + ['dev', 'str'], + ['force', 'int'], + ['rm_cfg', 'int']], req) def op_device_configure(self, _, req): Next, the libvirt patch: diff --git a/src/xend_internal.c b/src/xend_internal.c --- a/src/xend_internal.c +++ b/src/xend_internal.c @@ -3269,7 +3273,7 @@ xenDaemonDetachDevice(virDomainPtr domai if (virDomainXMLDevID(domain, xml, class, ref, sizeof(ref))) return (-1); return(xend_op(domain->conn, domain->name, "op", "device_destroy", - "type", class, "dev", ref, NULL)); + "type", class, "dev", ref, "force", "0", "rm_cfg", "1", NULL)); } Now, on to my question: I want to make sure I can do this without causing too many problems. In my testing, the libvirt change without the xen change won't cause any additional issues, but the xen change without the libvirt change will cause all 'virsh detach-disk' calls to fail. How should a change like this be handled? Submit the libvirt patch now, and sit on the Xen patch for a while? Or submit both and include a note that an upgrade will be necessary? Thanks, Ryan

[Libvir] New XML attributes for virtio
by Soren Hansen 07 Feb '08

07 Feb '08

Hi! I filed https://bugzilla.redhat.com/show_bug.cgi?id=431063 yesterday to track this issue. Quoting the bug report: "To use the new virtio capabilites available in kvm 60, special command line paramaters need to be passed to kvm. There should be a way to specify that a device should use virtio in the libvirt xml. I propose adding a "model" attribute to the interface element in the XML to be able to specify the type of NIC to emulate, e.g. 'virtio'. For the disk virtio I propose adding an 'interface' attribute to target element (inside the disk element). This interface could then be set to 'virtio', 'ide', 'scsi', etc.." Since I wrote the bug report, I noticed there's no way to specify which graphics card, you'd like to emulate. A 'model' attribute could probably be added to the graphics element as well. Comments? -- Soren Hansen Ubuntu Server Team http://www.ubuntu.com/

[Libvir] dumpxml define not idempotent due to <bootlader/> tag
by Guido Guenther 07 Feb '08

Hi, when using "virsh dumpxml <domain> > xmlfile" on a running paravirt xen domain that has no bootloader entry whatsoever I get: ... <bootloader/> <os> <type>linux</type> <kernel>/boot/vmlinuz-vm</kernel> <initrd>/boot/initrd.img-vm</initrd> <cmdline>root=/dev/sda1 ro </cmdline> </os> ... reimporting this via "virsh define xmlfile" and then dumping again gives something like: ... <bootloader/> <os> <type>linux</type> </os> ... since a bootloader tag is found the kernel and initrd entries are being dropped. My hack is to ignore empty bootloader statements for the moment: diff --git a/src/xend_internal.c b/src/xend_internal.c index fd38a61..5428cd7 100644 --- a/src/xend_internal.c +++ b/src/xend_internal.c @@ -1438,9 +1438,6 @@ xend_parse_sexp_desc(virConnectPtr conn, struct sexpr *root, if (tmp != NULL) { bootloader = 1; virBufferVSprintf(&buf, " <bootloader>%s</bootloader>\n", tmp); - } else if (sexpr_has(root, "domain/bootloader")) { - bootloader = 1; - virBufferVSprintf(&buf, " <bootloader/>\n"); } tmp = sexpr_node(root, "domain/bootloader_args"); if (tmp != NULL && bootloader) { Would that be the right place to fix this?

[Libvir] [PATCH] Fix the function that remove the element of the hash table.
by Hiroyuki Kaguchi 07 Feb '08

07 Feb '08

There are two logic error and a unnecessary else-statement in virHashRemoveSet function. This patch fix the following. (1/3) The logic error that use released memory area. (2/3) The logic error that doesn't remove elements. (3/3) Unnecessary else-statement. (1/3) The logic error that use released memory area. This bug causes the crash of virt-manager or virsh. If "virsh undefine" command is executed, "Segmentation Fault" is caused.

Hum, I don't like too much adding more exported symbols > Alternative is to not build with -Winline. That sounds a weak way to try to avoid a problem, we should not rely on just compiler options to get the code to compile and link. My preference would be to use the patch to make them real internal APIs without exporting all the functions, I think only xstrtol_i is used by external programs (virsh and qemud), and maybe we can add only that one to the list of exported symbols.

[Libvir] Remove more useless if tests before "free"-like functions.
by Jim Meyering 07 Feb '08

07 Feb '08

A few new uses of already-checked functions were added recently, and I've added xmlXPathFreeObject to the list, so that exposed a bunch more. ----------------------------------------------------------- Remove more useless if tests before "free"-like functions. * build-aux/useless-if-before-free: Rename from ... * build-aux/find-unnecessary-if-before-free: ... this. Remove file. Also changed it so that new names are no longer hard-coded in the script. Instead, they're supplied via options: * Makefile.cfg (useless_free_options): Define. Add xmlXPathFreeObject to the list of free-like functions it detects. * Makefile.maint (sc_avoid_if_before_free): Reflect script renaming. * .x-sc_avoid_if_before_free: Likewise. * src/openvz_conf.c (openvzParseXML): Remove useless "if"-before-free. * src/qemu_conf.c (qemudParseXML, qemudParseNetworkXML): Likewise. * src/virsh.c (cmdVNCDisplay, cmdTTYConsole, cmdDetachInterface): (cmdDetachDisk): Likewise. * src/xm_internal.c (xenXMConfigSetIntFromXPath): Likewise. (xenXMConfigSetStringFromXPath, xenXMParseXMLToConfig): Likewise. (xenXMDomainAttachDevice, xenXMAttachDisk, xenXMAttachInterface): (xenXMDomainDetachDevice): Likewise. * src/xml.c (virXPathString): Likewise. * tests/xmlrpctest.c (checkRequestValue): Likewise.

[Libvir] python/libvir.c returning wrong value on error?
by Cole Robinson 07 Feb '08

07 Feb '08

Hi all, Looking at python/libvir.c, all the custom functions return VIR_PY_NONE on error. This unfortunately doesn't map well to some of the generated python bindings which expect an error val of -1. So if these commands fail, no exception will be thrown at the python level. (Ex. virDomainGetAutostart, virDomainGetVcpus and their python equiv.) I'm wondering where the fix should be: in python/libvir.c, changing these error return values, or in the generator somewhere? Thanks, Cole

Hi, With gcc-4.3.0 (from Fedora rawhide), some new warnings are thrown up. The following three patches fixes them. The first two are straightforward, I think, but perhaps people might prefer to remove -Winline from our warning flags rather than apply the last patch. Cheers, Mark. --

[Libvir] [PATCH] change a Disk/Nic of inactive domain
by S.Sakamoto 06 Feb '08

06 Feb '08

Hi The libvirt on Xen-3.03 does not have the function that add/change/delete a Disk/NIC of inactive domain. So, I made a patch which enabled add/change/delete of Disk/NIC of inactive domain. This patch will be able to change "disk" or "vif" parameter in configuration file with "attach-disk","attach-interface", "attach-device", "detach-disk", "detach-interface" and "detach-device" command, like "setmem" or "setvcpus". Thanks, Shigeki Sakamoto.

[Libvir] don't use virBufferAdd with string literals
by Jim Meyering 06 Feb '08

06 Feb '08

I noticed a little glitch here: src/xml.c: virBufferAdd(buf, "(usbdevice tablet)", 13); src/xml.c: virBufferAdd(buf, "(usbdevice tablet)", 18); So I mounted a campaign to remove all such uses of virBufferAdd and make sure no more sneak back in. First, I added this definition: #define virBufferAddLit(buf_, literal_string_) \ virBufferAdd (buf_, "" literal_string_ "", sizeof literal_string_ - 1) The empty double quotes ensure that you get a syntax error if you pass anything other than a string literal in the 2nd parameter. The idea being to change, e.g., the above examples to this: virBufferAddLit(buf, "(usbdevice tablet)"); FYI, I converted almost all of the uses of virBufferAdd like this: git grep -l -w virBufferAdd|xargs perl -pi -e \ 's/virBufferAdd( *$[^,]+, *"[^"]*"), *-?\d+ *$/virBufferAddLit$1)/' About 20 more uses spanned two or more lines. I did them manually. Here's the complete change: Eliminate all uses of virBufferAdd with string literals. * Makefile.maint (sc_prohibit_virBufferAdd_with_string_literal): New rule. * src/buf.h (virBufferAddLit): Define. * src/conf.c (virConfSaveValue): Use virBufferAddLit, in place of virBufferAdd everywhere possible. (virConfSaveEntry): Likewise. * src/qemu_conf.c (qemudGenerateXML, qemudGenerateNetworkXML): Likewise. * src/qemu_driver.c (qemudGetFeatures, qemudGetCapabilities): Likewise. * src/test.c (testDomainDumpXML, testNetworkDumpXML): Likewise. * src/xen_internal.c (xenHypervisorMakeCapabilitiesXML): Likewise. * src/xend_internal.c (xend_parse_sexp_desc_os): Likewise.

(virDomainParseXMLGraphicsDescImage): Likewise. (virDomainParseXMLGraphicsDescVFB, virDomainParseXMLOSDescHVM): Likewise. (virDomainParseXMLOSDescPV, virDomainParseXMLDiskDesc): Likewise.

[Libvir] removing trailing blanks (and keeping them away)
by Jim Meyering 05 Feb '08

05 Feb '08

Any objection to a mass removal of trailing blanks? [ If you haven't yet been adversely affected by e.g., pointless conflicts due solely to differences in white space, count yourself lucky, and chalk it up to not having to deal with many branches. The sooner we do this the better, IME. ] I'm proposing two things: - remove all trailing blanks - add a "make syntax-check" check to ensure that no new ones are added There aren't that many, but the change would affect many files. IMHO, such a change should wait until after big patches like Dan's StorageAPI changes are in. Obviously, one would not change .png and .gif files, and they would be exempted from the mechanical check.

Don't add things to xenUnifiedDriver structure -- this structure should go away eventually. (See the comment in src/xen_unified.h).

[Libvir] libvirt & vde_switch
by Loic Dachary 05 Feb '08

05 Feb '08

In reply to http://www.redhat.com/archives/libvir-list/2007-April/msg00177.html an area where vde_switch support is usefull is an unprivileged user running tests. A test suite involving the creation of qemu instances thru libvirt should not be forced to create a bridge or alter the iptables configuration. With vde_switch and slirpvde multiple qemu instances can be run without altering the network configuration of the host. I hope it helps. Cheers

[Libvir] mark some diagnostics for translation
by Jim Meyering 04 Feb '08

04 Feb '08

This makes it so some diagnostics emitted via the error function are checked for use of "_(...)" when you run "make syntax-check", and fixes the ones that lacked that: Enable the sc_unmarked_diagnostics test and correct all violations involving the "error" function. * Makefile.cfg (local-checks-to-skip): Remove from skip list. Then, at the end, a second patch: Mark a string for translation. * src/virsh.c: Add a "%s" and wrap with _(...). Note that technically, it doesn't make sense to translate a diagnostic like this (there are several like this): error (conn, VIR_ERR_RPC, _("maxids > REMOTE_DOMAIN_ID_LIST_MAX")); However, if it's worth emitting the diagnostic, then I think it's worth making it a little more useful to someone not reading the code, e.g., too many domains (maximum is %d) If no one objects, I'll convert the ones below.

[Libvir] mark more translatable messages
by Jim Meyering 04 Feb '08

04 Feb '08

This change marks for translation some more messages. It adds a few new ones, too, e.g., replacing "domain" with _("failed to parse domain description") in two places. Likewise, there are some like this: - virXendError (conn, VIR_ERR_NO_MEMORY, "strdup"); + virXendError (conn, VIR_ERR_NO_MEMORY, _("strdup failed")); The two new grep invocations in Makefile.maint handle two situations: First, when the entire statement is on a single line (ends in ";"). The second grep (with -A1) is to get the diagnostics that appear on the line following the function name. Hence where the first line ends in ",". With checks like this, it's nice if you can assume no trailing blanks in the code base. IMHO, that would be a nice change to make soon, but it's more invasive. Enable more checks for unmarked messages; fix violators. * Makefile.maint (sc_unmarked_diagnostics): Check for more functions. * src/conf.c (virConfParseValue): Remove trailing space in diagnostic. * src/libvirt.c (do_open, virDomainMigrate): Mark diagnostics. * src/xend_internal.c (do_connect, xenDaemonDomainDumpXMLByID): Likewise.

[Libvir] virsh vncdisplay fix
by John Levon 03 Feb '08

03 Feb '08

I have an old HVM guest defined in 3.0.4, and now I'm running 3.1.2 and libvirt 0.4.0. The config looks like this: (domain (image (hvm (vnc 1) (vncdisplay 0) (device (vfb (location localhost:5900) (vncdisplay 0) (uuid ...) The libvirt code looks like this: 1757 /* Graphics device (HVM <= 3.0.4, or PV <= 3.0.3) vnc config */ 1758 if ((hvm && xendConfigVersion < 4) || 1759 (!hvm && xendConfigVersion < 3)) { 1760 tmp = sexpr_fmt_node(root, "domain/image/%s/vnc", hvm ? "hvm" : "linux"); So we don't see the 'vnc 1' at the top. But the code to parse device/vfb doesn't expect this config either: 1685 tmp = sexpr_node(node, "device/vfb/type"); The patch below replaces the later version check with something that copes correctly with the "upgrade" case. regards john 2008-01-15 John Levon <levon(a)movementarian.org> * src/xend_internal.c: fix VNC parsing of old Xen domains on newer Xen versions. diff -prauN libvirt-0.4.0/src/xend_internal.c libvirt-new/src/xend_internal.c --- libvirt-0.4.0/src/xend_internal.c 2007-12-17 15:05:27.000000000 -0800 +++ libvirt-new/src/xend_internal.c 2008-01-14 18:42:08.895060570 -0800 @@ -1371,6 +1371,7 @@ xend_parse_sexp_desc(virConnectPtr conn, unsigned char uuid[VIR_UUID_BUFLEN]; char uuidstr[VIR_UUID_STRING_BUFLEN]; int vif_index = 0; + int found_graphics = 0; if (root == NULL) { /* ERROR */ @@ -1683,6 +1684,7 @@ xend_parse_sexp_desc(virConnectPtr conn, if (tmp && !strcmp(tmp, "sdl")) { virBufferVSprintf(&buf, " <input type='mouse' bus='%s'/>\n", hvm ?

[Libvir] [PATCH] Pull vc-list-files from gnulib, and update.
by Jim Meyering 01 Feb '08

01 Feb '08

Now that I've added the vc-list-files script to gnulib, this patch makes libvirt's bootstrap pull it from there. Changes from the previous version of the script: I reintroduced support for mercurial (only lightly tested), and rearranged the directory-existence tests so git is first.

No, I wasn't able to get virt-manager running. Probably the same problems as you are having: building Python modules (specifically, libvirtmod.dll) which can work from the Win32 version of python, with gcc/MinGW, proves to be very hard.

[Libvir] [PATCH] avoid virsh hang due to missing virDomainFree(dom) call
by Jim Meyering 30 Jan '08

Without the following patch, this command would hang printf 'domuuid fc4\ndomstate fc4\n' \ | ./virsh --connect test://$PWD/../docs/testnode.xml with this stack trace: __lll_lock_wait ... _L_lock_105 ... __pthread_mutex_lock ... virUnrefDomain (domain=0x6a8b30) at hash.c:884 virDomainFree (domain=0x6a8b30) at libvirt.c:1211 cmdDomstate (ctl=0x7fffea723390, cmd=0x6a8b10) at virsh.c:677 vshCommandRun (ctl=0x7fffea723390, cmd=0x6a8b10) at virsh.c:4033 main (argc=3, argv=0x7fffea7234e8) at virsh.c:5015 The problem is that cmdDomuuid didn't call virDomainFree(dom), so cmdDomstate hangs trying to do the Unref.

[Libvir] VIR_DOMAIN_NOSTATE
by Russ Blaine 29 Jan '08

29 Jan '08

On Solaris-based xen 3.1.2 I am seeing virDomainGetInfo() often returning VIR_DOMAIN_NOSTATE in dominfo.state for domUs that are powered on and running. What exactly does VIR_DOMAIN_NOSTATE mean? Why does it exist? I suspect it is a catch-all in the API for hosts that don't entirely have their act together, that do not always return a valid guest state. Is that the case? Is anyone else seeing this on Xen? -- ----------------------------------------------------- Russ Blaine | Solaris Kernel | russell.blaine(a)sun.com

[Libvir] PATCH: Fix block device numbers for virDomainBlockStats
by Daniel P. Berrange 29 Jan '08

29 Jan '08

As mentioned in this thread: http://www.redhat.com/archives/libvir-list/2008-January/msg00475.html The code for calculating block devices numbers has a number of flaws. This patch fixes the flaws and adds a comprehensive test program to validate it. The test program also validates invalid cases. NB, this code is actually now more perfect than Xen, since Xen doesn't handle SCSI disks > sdp, even though you can go all the way to sdhv. The rules are: * hdNM: N=a-t, M=1-63, major={IDE0_MAJOR -> IDE9_MAJOR} * sdNM: N=a-z,aa-hw, M=1-15, major={SCSI_DISK0_MAJOR -> SCSI_DISK15_MAJOR} * xvdNM: N=a-p, M=1-15, major=XENVBD_MAJOR Which translates to the formulas xvdNM: (XENVBD_MAJOR * 256) + (disk * 16) + part; sdNM: (majors[disk/16] * 256) + ((disk%16) * 16) + part hdNM: (majors[disk/2] * 256) + ((disk % 2) * 63) + part; The SCSI/IDE formulas lookup the major number in a table since they are allocated non-contigously. The test case validates these: $ ./statstest xvda == 51712 OK xvda1 == 51713 OK xvda15 == 51727 OK xvdp == 51952 OK xvdp1 == 51953 OK xvdp15 == 51967 OK xvdq == -1 OK xvd1 == -1 OK xvda16 == -1 OK xvda0 == -1 OK hda == 768 OK hda1 == 769 OK hda63 == 831 OK hdd == 5695 OK hdd1 == 5696 OK hdd63 == 5758 OK hdt == 23359 OK hdt1 == 23360 OK hdt63 == 23422 OK hdu == -1 OK hd1 == -1 OK hda64 == -1 OK hda0 == -1 OK sda == 2048 OK sda1 == 2049 OK sda15 == 2063 OK sdp == 2288 OK sdp1 == 2289 OK sdp15 == 2303 OK sdq == 16640 OK sdq1 == 16641 OK sdq15 == 16655 OK sdz == 16784 OK sdz1 == 16785 OK sdz15 == 16799 OK sdaa == 16800 OK sdaa1 == 16801 OK sdaa15 == 16815 OK sdab == 16816 OK sdab1 == 16817 OK sdab15 == 16831 OK sdba == 17216 OK sdba1 == 17217 OK sdba15 == 17231 OK sdiv == 34800 OK sdiv1 == 34801 OK sdiv15 == 34815 OK sdix == -1 OK sd1 == -1 OK sda16 == -1 OK sda0 == -1 OK /dev == -1 OK /dev/ == -1 OK /dev/xvd == -1 OK /dev/xvda == 51712 OK /dev/xvda1 == 51713 OK /dev/xvda15 == 51727 OK The patch also fixes a couple of error codes to be INTERNAL_ERROR rather than NO_SUPPORT, because the latter is for APIs which are not supported, where as the conditions here are simply errors that shouldn't happen.

[Libvir] update after changing XML
by Maxwell Bottiger 29 Jan '08

29 Jan '08

Hi, I changed some of the XML for a qemu virtual machine. The original file was generated by virt-manager, but I wanted to use bridged networking as described in the documentation on the libvirt website. Is there something I need to for my xml changes to show up in the virtual machine? Right now my VM will not start because it's looking for it's old network configuration. -Max This e-mail and any files transmitted with it may be proprietary and are intended solely for the use of the individual or entity to whom they are addressed.

[Libvir] [PATCH] virtinst: don't expect non-root users to have block device access
by Guido Guenther 29 Jan '08

29 Jan '08

Hi, attached patch drops the assumption that a non-root user has read access to the guest OSes partition - he doesn't need to since all interaction is handled via libvirt and giving the user read access for a simple MBR block read test seems like overkill. Please apply if appropriate, patch is against current hg.

[Libvir] [PATCH] Avoid link errors with "configure --disable-shared".
by Jim Meyering 29 Jan '08

29 Jan '08

I tried to build static binaries in the usual libtool way, via "configure --disable-shared" and got some link errors due to the tests linking only with shared-lib-related files. Here's the fix: Avoid link errors with "configure --disable-shared". * tests/Makefile.am (LDADDS): Add ../src/libvirt.la, so that "configure --disable-shared" no longer provokes link errors. --- tests/Makefile.am | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/tests/Makefile.am b/tests/Makefile.am index dfd9e34..1b5f287 100644 --- a/tests/Makefile.am +++ b/tests/Makefile.am @@ -33,6 +33,7 @@ LDADDS = \ $(SASL_LIBS) \ $(WARN_CFLAGS) \ $(LIBVIRT) \ + ../src/libvirt.la \ ../gnulib/lib/libgnu.la \ $(COVERAGE_LDFLAGS) -- 1.5.4.rc5.1.g0fa73

[Libvir] 0/8 add syntax checks
by Jim Meyering 29 Jan '08

29 Jan '08

A few days ago I wrote a patch eliminating all of the useless if tests of the form "if (foo) free (foo);". In general, when making such a global change, I prefer to add a check so that it is easy to ensure mechanically that the new violations don't sneak back in. So I wrote a script to detect the above, then another to perform the "remove-if-cond" part as a double check against my detect-and-manually-remove work. Once you can mechanically detect the offending pattern, it's good to make it as easy as possible to check for recurrence. In other projects, I've used "make syntax-check", because most such tests are syntax-related and detectable using tools like grep. The first patch simply removes the useless if tests. Following it, I introduce a "make syntax-check" framework similar to what I use in coreutils. In it, most tests are disabled, except the new one that tests for the unnecessary "if"-before-free. In the following 6 patches, I enable new tests one by one, and correct the violations each one exposes. I deliberately keep these tests in a separate Makefile.maint file, and pull them in via GNUmakefile so that they are not subject to the burdensome portability constraints associated with regular Makefile.am contents. I.e., if you run "make syntax-check", you are expected to have GNU make as well as a reasonable set of working tools. Thus, we don't have to worry about whether egrep works or whether e.g., perl is present. Jim

Sorry for late reply, I was on holiday yesterday. For the build error, looks like a regression because of some recently added / updated code. I'll have to boot up my Windows machine and take a look. Versions of the packages used: MinGW & MSYS "candidate" versions (specifically, gcc 4 is required) GnuTLS 1.6.3 (binary for Windows on their site) Make sure you install it in a location _without_ a space in the path (ie. not the default). You have to hack the *.la files to correct the hard-coded paths. libxml2 2.6.30 (I compiled from source, but there are also binaries available) My PortableXDR library. You should be able to use the binaries from that location. Within the installer you'll find a 'libvirt.dll' + all the *.dll that it requires. Supposedly this DLL will work on MS VC++, but obviously I haven't tested this. The thing to do is to try it.

[Libvir] Re; virDomainBlockStats
by Gareth Bult 27 Jan '08

27 Jan '08

Hi, I've a number of servers running XEN and am trying to write some code to monitor them through libvirt. (Xeon/Dual Core/Ubuntu Gutsy/Xen 3.1) All was going well until I got to virDomainBlockStats and it simply refused to accept my coding .. My solution (the code now works) is to change the following; src/stats_linux.c: #ifndef XENVBD_MAJOR #define XENVBD_MAJOR 3 // <--- I changed this! /*#define XENVBD_MAJOR 202*/ #endif device = XENVBD_MAJOR * 256 + 1 + minor /* * 16 */; <-- this too! It now seems to give me some meaningful numbers without feeding my any error messages. Can anyone tell me "why" I needed to do this? I'm using "xvda" as the device path .. tried every other device name I could think of with out any good results ... ????? tia Gareth.

Mmm, Ok .. I've pretty much spent the last week getting Xen 3.2 to function "properly" built entirely from raw XEN sources using Xen's documentation. AIO is still a flakey as hell, one time through the loop and the instance seems to work, second time around it won't start and neither will anything else. I have file: based instances running just fine .. my guess is the unload problem is still there, but the kernel logging is gone and they've created a critical system lock-up in it's place. Is there any documentation to the effect that "file" is bad?? The official XEN documentation lists "file" as the standard and makes no mention of "aio". Currently I'm mounting my image on gluster filesystems and I'm getting 70Mb/sec so I'm not unhappy with the performance, and I've had no issues recently with crashes. ... more information would be useful if you have it. Whereas I'm happy to accept that aio is better in principle, as far as I can see although it may work for you, I've now tried it in a number of different configurations on a number of machines and it's simply unusable. tia Gareth. ----- Original Message ----- step 3.: "Daniel P.

That must be a flaw in Ubuntu's kernels. tap:aio works flawlessly in Fedora / RHEL and is the only supported option, because file: has catastrophic data loss issues during host crashes.

FW: [Libvir] Libvirt on windows
by Gabriel Kaufmann 27 Jan '08

Hi, I'm still unable to build (see output files attached). This is from the sources I downloaded from ftp://libvirt.org/libvirt/libvirt-cvs-snapshot.tar.gz When running configure I get a popup error message that libconf-2.dll is missing. Looking at MinGW site, I found version 1.11 of libconv. Do I have to use a later version? If yes where can I find it. I'm having problem understanding which libraries and versions I should use for the compilation. Do you have a more detailed list of packages to install in MinGW. If you can send me this lis, I'll start from the beginning using a new (clean) XP installation. Can I just use the binaries compiled in https://www.redhat.com/archives/libvir-list/2008-January/msg00072.html ? I want to be able to connect to the Xen server using libvirt from Microsoft Visual Studio using c/C++. Gaby -----Original Message----- From: Richard W.M.

[Libvir] A sample program to create a Linux Container
by Dave Leskovec 26 Jan '08

26 Jan '08

Attached is a simple program that uses the clone() function to create a container. This is not intended as a patch - just an example of what creating a Linux Container looks like. Something along these lines will be used by the Linux Container driver to start the domain. The code run within this container is really simple. It just mounts the /proc file system and then dumps the ps output to a file showing that the container is in separate process space. To run this you will need to have PID namespaces support enabled. Turn on CONFIG_PID_NS when compiling the kernel. You must run the program as root or the clone() call will fail. Any questions or comments are welcome.

There's a couple of odd things about this. Firstly: In file included from ../gnulib/lib/sys/stat.h:28, from remote_internal.c:36: ../gnulib/lib/sys/stat.h: In function 'rpl_mkdir': ../gnulib/lib/sys/stat.h:272: warning: unused parameter 'mode' In file included from remote_internal.c:61: getaddrinfo.h:38:19: error: netdb.h: No such file or directory In file included from remote_internal.c:61: getaddrinfo.h: At top level: getaddrinfo.h:199: error: redefinition of 'struct addrinfo' getaddrinfo.h:214: error: conflicting types for 'gai_strerrorA' c:\mingw\bin\../lib/gcc/mingw32/4.2.1-sjlj/../../../../include/ws2tcpip.h:309: error: previous definition of 'gai_strerrorA' was here According to ./configure, <netdb.h> header file wasn't found, as expected, but the Gnulib implementation of getaddrinfo shouldn't be trying to include it in this case. In Gnulib's getaddrinfo.h we have: #ifdef HAVE_NETDB_H # include <netdb.h> #endif But I think you're including some other <getaddrinfo.h> from somewhere else. My version of MinGW doesn't have any file called getaddrinfo.h (which is why we're using the one from Gnulib in the first place), so I suspect either you're using some later version of MinGW or else you've got MinGW & Cygwin files mixed up, or you've got some other implementation of getaddrinfo installed. Secondly: ../qemud/remote_protocol.h:509: error: expected specifier-qualifier-list before 'u_int64_t' In this file from CVS, line 509 is: typedef struct remote_domain_get_max_vcpus_args remote_domain_get_max_vcpus_args; and I don't see how this line can provoke the error. You'll need to use the versions of qemud/remote_protocol.[ch] from CVS, along with PortableXDR (see yesterday's posting) or my hacked up xdr-4.0-mingw5 library.

[Libvir] Libvirt on windows

Hi, Did anybody managed to compile libvirt-0.4.0 on windows. I tried following instructions on http://libvirt.org/windows.html which offer compiling in Cygwin. This doesn't work because of inconsistency with winsock2. If I change manually the HAVE_WINSOCK2 macro and make some changes in the code (see https://www.redhat.com/archives/libvir-list/2008-January/msg00344.html ) I manage to compile but after compiling virsh doesn't work (don't manage to connect to the host and returns Bad Address immediately) Then I tried following the (not so detailed) instructions in https://www.redhat.com/archives/libvir-list/2008-January/msg00017.html I get error compilation: In file included from remote_internal.c:73: ../qemud/remote_protocol.h:1218:2: error: #endif without #if remote_internal.c: In function 'remoteDomainGetMaxMemory': remote_internal.c:1581: error: 'remote_domain_get_max_memory_ret' has no member named 'memory' remote_internal.c: In function 'remoteDomainSetMaxMemory': remote_internal.c:1591: error: 'remote_domain_set_max_memory_args' has no member named 'memory' remote_internal.c: In function 'remoteDomainSetMemory': remote_internal.c:1608: error: 'remote_domain_set_memory_args' has no member named 'memory' remote_internal.c: In function 'remoteDomainGetInfo': remote_internal.c:1634: error: 'remote_domain_get_info_ret' has no member named 'max_mem' remote_internal.c:1635: error: 'remote_domain_get_info_ret' has no member named 'memory' remote_internal.c:1636: error: 'remote_domain_get_info_ret' has no member named 'nr_virt_cpu' remote_internal.c:1637: error: 'remote_domain_get_info_ret' has no member named 'cpu_time' remote_internal.c: In function 'remoteDomainMigratePrepare': remote_internal.c:1846: error: 'remote_domain_migrate_prepare_args' has no member named 'flags' remote_internal.c:1847: error: 'remote_domain_migrate_prepare_args' has no member named 'dname' remote_internal.c:1848: error: 'remote_domain_migrate_prepare_args' has no member named 'resource' remote_internal.c: In function 'remoteDomainMigratePerform': remote_internal.c:1882: error: 'remote_domain_migrate_perform_args' has no member named 'flags' remote_internal.c:1883: error: 'remote_domain_migrate_perform_args' has no member named 'dname' remote_internal.c:1884: error: 'remote_domain_migrate_perform_args' has no member named 'resource' remote_internal.c: In function 'remoteDomainMigrateFinish': remote_internal.c:1911: error: 'remote_domain_migrate_finish_args' has no member named 'flags' make[2]: *** [libvirt_la-remote_internal.lo] Error 1 make[2]: Leaving directory `/data/cvs/libvirt/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/data/cvs/libvirt' Can anyone tell help?

[Libvir] PATCH: Remove use of PKG_CHECK_EXISTS
by Daniel P. Berrange 23 Jan '08

23 Jan '08

This patch removes the use of PKG_CHECK_EXISTS which is only available in new versions of pkg-config. Instead we use the 3rd and 4th args of the PKG_CHECK_MODULES macro to control the if-found/not-found behaviour. This allows us to auto-disable features if they're missing, rather than aborting the configure run. This patch also updates the SASL tests to support the value 'check' for auto-enable/disable like the rest of the modules. With this applied I can successfully run the following on RHEL-4 hosts with the default RPMs installed ./autogen.sh --without-xen make make dist Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|
