I propose enhancing the XML; on output, libvirt should produce: <memory units='k'>2048</memory> => 2048 * kibibyte the output unit must remain the same as it has always been, but the new attribute will make it easier for humans reading the XML to spot blunders like what spawned this thread. On input, the optional attribute is more useful - we can use it to provide a multiplier (of course, the result will be rounded up to k, and again rounded up to any higher granularity per the hypervisor): b => bytes k, KiB => kibibyte (1024) KB => kilobyte (1000) M, MiB => mebibyte (1024*1024) MB => megabyte (1000000) and so on for at least G and T (do we need P, E, Z, or Y? and I'm jealous if you have a machine with 1Y memory).

[libvirt] [PATCH 0/3] Forbid migration with cache != none
by Jiri Denemark 23 Feb '12

23 Feb '12

Migrating qemu domains with disks using cache != none is unsafe unless the disk images are stored on coherent clustered filesystem. Thus we forbid migrating such domains unless VIR_MIGRATE_UNSAFE flags is used. This series uses similar aproach to forbidding unsafe PCI passthrough or disk format probing when we forbade those by default with the possibility to force them. Domain configuration is only checked on source, which makes migrating affected domains from an old libvirt to the new one possible. Migrating back is impossible since destination libvirtd would complain about unknown flag (the flag is not filtered so it gets to the destination even though it's not really used there). However, users of clustered filesystems now have to always pass the new flag to be able to migrate because libvirtd would think they are doing something unsafe. Perhaps we should provide a system wide (i.e., /etc/libvirt/qemu.conf) tunable which would disable cache mode checking for all domains at once? I was also wondering if we should rather use more specific name for both the error code and flag, such as VIR(_ERR)?_MIGRATE_UNSAFE_CACHE (or ...UNSAFE_DISK) in the case we find other unsafe conditions...

[libvirt] Cluster_size parameter issue on qcow2 image format
by Pankaj Rawat 23 Feb '12

23 Feb '12

I have been working o the qcow2 image format , I theory regarding cluster size it is written that as the size of cluster increase performance should increase. But something surprising happen The performance is degrading as the size of cluster increased from 64K to 1M ( during expansion of qcow2 image) can any one tell why ?

[libvirt] [PATCH] libvirt-guests: Enable parallel operations and improve error handling
by Peter Krempa 22 Feb '12

22 Feb '12

This patch modifies the libvirt-guests init script to enable parallel shiutdown on guest machines and gets rid of error messages if the client is unable connect to the URI specified in the config file. --- Simultaneous shutdown of machines may speed up the shutdown process as the shutdown sequence of guests often consists of timeouts and storage un-intensive tasks. Simultaneous resume of machines was already supported, although not documented well enough. This patch also checks if connection to the URI can be done, and prints a error message if it's not the case. This get's rid of unrelevant and repeated error messages if the URI is unreachable. The last improvement is while using managed-save. Transient domains are excluded from the save sequence to get rid of error messages and a list of domains that are left behind is printed. Please tell me your suggestions how to improve this, as I'm not a bash "native speaker". tools/libvirt-guests.init.sh | 214 ++++++++++++++++++++++++++++++++++++++---- tools/libvirt-guests.sysconf | 10 ++- 2 files changed, 204 insertions(+), 20 deletions(-) diff --git a/tools/libvirt-guests.init.sh b/tools/libvirt-guests.init.sh index 367177e..c858747 100644 --- a/tools/libvirt-guests.init.sh +++ b/tools/libvirt-guests.init.sh @@ -78,8 +78,25 @@ run_virsh_c() { ( export LC_ALL=C; run_virsh "$@" ) } +test_connect() +{ + uri=$1 + + run_virsh "$uri" connect 2>/dev/null + if [ $? -ne 0 ]; then + eval_gettext "Can't connect to \$uri.

Hey, I recently setup ovirt/vdsm on one of my boxes. For some reason spice TLS was disabled through spice_tls = no in /etc/libvirt/qemu.conf. Then I created a VM, started it, and had troubles connecting to it with spicec. After investigating (thanks djasa), I realized that qemu was started with some encrypted SPICE channels but with no TLS port configured, which explained why I couldn't connect. https://bugzilla.redhat.com/show_bug.cgi?id=790436 was filed against libvirt about this, but now we are wondering how to best fix things in libvirt. What is currently happening is that libvirt doesn't warn when a domain has <channel name='main' mode='secure'/> with spice_tls = no in qemu.conf, and it adds the corresponding tls-channel=main to qemu command-line, but doesn't set a TLS port (if one is set it's silently ignored). There are at least two ways of solving this problem in libvirt: * either the current behaviour is kept, but "tls-channel=main" is not added to qemu command line when spice-tls is disabled. The drawback of this is that some security options that have been explicitly set in the domain XML are silently ignored * or the current behaviour is changed, and in this situation (SPICE secure channels in the XML, but TLS disabled in qemu.conf), libvirt errors out, which would change the current behaviour. This has been discussed on the libvirt mailing list (cc'ed) in this thread: https://www.redhat.com/archives/libvir-list/2012-February/msg00656.html Before making a decision, we were wondering what behaviour oVirt would expect in this case (error or silently ignoring the secure channels), and if a setup with spice_tls = no in /etc/libvirt/qemu.conf is something widely deployed that you have to support, or if it's more of an experimental feature at this point. Thanks for any input you can give on this matter, Christophe

Previously we would have: "os type 'hvm' & arch 'idontexist' combination is not supported" Now we get "No guest options available for arch 'idontexist'" or if options available but guest OS type not applicable: "No os type 'xen' available for arch 'x86_64'" --- src/conf/capabilities.c | 28 ++++++++++++++++++++++++---- src/conf/capabilities.h | 9 ++++++--- src/conf/domain_conf.c | 13 +++++++++++-- 3 files changed, 41 insertions(+), 9 deletions(-) diff --git a/src/conf/capabilities.c b/src/conf/capabilities.c index d44ce1b..542bf03 100644 --- a/src/conf/capabilities.c +++ b/src/conf/capabilities.c @@ -497,6 +497,26 @@ virCapabilitiesAddGuestFeature(virCapsGuestPtr guest, return NULL; } +/** + * virCapabilitiesSupportsGuestArch: + * @caps: capabilities to query + * @arch: Architecture to search for (eg, 'i686', 'x86_64') + * + * Returns non-zero if the capabilities support the + * requested architecture + */ +extern int +virCapabilitiesSupportsGuestArch(virCapsPtr caps, + const char *arch) +{ + int i; + for (i = 0 ; i < caps->nguests ; i++) { + if (STREQ(caps->guests[i]->arch.name, arch)) + return 1; + } + return 0; +} + /** * virCapabilitiesSupportsGuestOSType: @@ -520,7 +540,7 @@ virCapabilitiesSupportsGuestOSType(virCapsPtr caps, /** - * virCapabilitiesSupportsGuestOSType: + * virCapabilitiesSupportsGuestOSTypeArch: * @caps: capabilities to query * @ostype: OS type to search for (eg 'hvm', 'xen') * @arch: Architecture to search for (eg, 'i686', 'x86_64') @@ -529,9 +549,9 @@ virCapabilitiesSupportsGuestOSType(virCapsPtr caps, * requested operating system type */ extern int -virCapabilitiesSupportsGuestArch(virCapsPtr caps, - const char *ostype, - const char *arch) +virCapabilitiesSupportsGuestOSTypeArch(virCapsPtr caps, + const char *ostype, + const char *arch) { int i; for (i = 0 ; i < caps->nguests ; i++) { diff --git a/src/conf/capabilities.h b/src/conf/capabilities.h index 38d07c4..421030d 100644 --- a/src/conf/capabilities.h +++ b/src/conf/capabilities.h @@ -237,12 +237,15 @@ virCapabilitiesAddGuestFeature(virCapsGuestPtr guest, int toggle); extern int +virCapabilitiesSupportsGuestArch(virCapsPtr caps, + const char *arch); +extern int virCapabilitiesSupportsGuestOSType(virCapsPtr caps, const char *ostype); extern int -virCapabilitiesSupportsGuestArch(virCapsPtr caps, - const char *ostype, - const char *arch); +virCapabilitiesSupportsGuestOSTypeArch(virCapsPtr caps, + const char *ostype, + const char *arch); extern const char * diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 85a2058..b0c3fa6 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -7581,9 +7581,18 @@ static virDomainDefPtr virDomainDefParseXML(virCapsPtr caps, def->os.arch = virXPathString("string(./os/type[1]/@arch)", ctxt); if (def->os.arch) { - if (!virCapabilitiesSupportsGuestArch(caps, def->os.type, def->os.arch)) { + if (!virCapabilitiesSupportsGuestArch(caps, def->os.arch)) { virDomainReportError(VIR_ERR_INTERNAL_ERROR, - _("os type '%s' & arch '%s' combination is not supported"), + _("No guest options available for arch '%s'"), + def->os.arch); + goto error; + } + + if (!virCapabilitiesSupportsGuestOSTypeArch(caps, + def->os.type, + def->os.arch)) { + virDomainReportError(VIR_ERR_INTERNAL_ERROR, + _("No os type '%s' available for arch '%s'"), def->os.type, def->os.arch); goto error; } -- 1.7.7.5
