[libvirt] [PATCH v3] tools: Fix connect command
by Martin Kletzander 29 Apr '16

29 Apr '16

The man page says: "(Re)-Connect to the hypervisor. When the shell is first started, this is automatically run with the URI parameter requested by the "-c" option on the command line." However, if you run: virsh -c 'test://default' 'connect; uri' the output will not be 'test://default'. That's because the 'connect' command does not care about any virsh-only related settings and if it is run without parameters, it connects with @uri == NULL. Not only that doesn't comply to what the man page describes, but it also doesn't make sense. It also means you aren't able to reconnect to whatever you are connected currently. So let's fix that in both virsh and virt-admin add a test case for it.

[libvirt] [PATCH] send default USB controller in xml to destination during migration on PPC64
by Shivaprasad G Bhat 29 Apr '16

29 Apr '16

The default USB controller is not sent to destination as the older versions of libvirt(0.9.4 or earlier as I see in commit log of 409b5f54) didn't support them. For some archs where the support started much later can safely send the USB controllers without this worry. For now, changing the checks to allow PPC64 here. If we can track the historical support for other archs, the changes can be extrapolated to them too. The patch fixes a bug that, if the USB controller happens to occupy a slot after disks/interfaces and one of them is hot-unplugged, then the default USB controller added on destination takes the smallest slot number and that would lead to savestate mismatch and migration failure.

[libvirt] [PATCH 0/2] configure: Improve init script choice
by Andrea Bolognani 29 Apr '16

29 Apr '16

If not init script type is explicitly chosen by the user, we try to pick a good default based on the compilation OS. Unfortunately, in that situation our code only really does the right thing for old RHEL releases. Our reporting is sub-par, too. This series makes it so more distributions get the right init script installed by default and improves reporting.

[libvirt] Entering freeze for libvirt-1.3.4
by Daniel Veillard 29 Apr '16

29 Apr '16

We are in freeze ! I tagged the release candidate 1 in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ that looks fine with my very limited testing, but that's likely not indicative of the actual stability :) https://ci.centos.org/view/libvirt-project/ is rather positive though someone should look at a potential FreeBSD portability issue based on the report (or that could be that the Jenkins test need a bit of attention) Plan is to have RC2 on Friday and try to push 1.3.4 final from airport in Sunday (so there is a little bit of risk there). Please give it a try !

[libvirt] [PATCH] vz: fix disk enumeration
by Mikhail Feoktistov 28 Apr '16

28 Apr '16

If we want to delete all disks for container or vm we should make a loop from 0 to NumberOfDisks and always use zero index in PrlVmCfg_GetHardDisk to get disk handle. When we delete first disk after that numbers of other disks will be changed, start from 0 to NumberOfDisks-1. That's why we should always use zero index. --- src/vz/vz_sdk.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/vz/vz_sdk.c b/src/vz/vz_sdk.c index 8cc8430..70d61e5 100644 --- a/src/vz/vz_sdk.c +++ b/src/vz/vz_sdk.c @@ -3810,7 +3810,7 @@ prlsdkDetachDomainHardDisks(PRL_HANDLE sdkdom) prlsdkCheckRetGoto(pret, cleanup); for (i = 0; i < hddCount; ++i) { - pret = PrlVmCfg_GetHardDisk(sdkdom, i, &sdkdisk); + pret = PrlVmCfg_GetHardDisk(sdkdom, 0, &sdkdisk); prlsdkCheckRetGoto(pret, cleanup); pret = PrlVmDev_Remove(sdkdisk); -- 1.8.3.1

[libvirt] [PATCH 0/8] (incomplete) fix of "peer" address feature
by Laine Stump 28 Apr '16

28 Apr '16

This patch series fixes this feature enoough that it works: 1) emits "peer" attribute in formatted XML when present in the NetDef object, so that the config will "stick" 2) swaps "address" and "peer" for qemu, so that "address" consistently refers to the IP address used by the guest, and "peer" to the address used by the host. 3) ... and the rest *BUT* it doesn't address the sub-optimal naming of the new attribute, nor does it fix the documentation which is incorrect not only in its description, but also in the starting version number for QEMU support. Also, I'm skeptical that this new feature is useful for the types of lxc interfaces that are supported (macvtap i.e. "direct", and a veth connected to a bridge) - from my understanding, it would only be useful for a type='ethernet' interface (a tap/veth pair not connected to any bridge), and that isn't supported by lxc yet; for type='bridge' and type='network' (which is also connecting to a bridge) I don't see the use case. So I'm torn about whether these patches should be put in for this release in order to made the already-pushed code work, or if we should just hold off until we: 1) find/agree on a better name for the new attribute (see my earlier mail titled 'interface "peer address" patches are broken for details on my opinion) 2) decide if it's actually useful to support the "peer" address for type='network|bridge" in lxc (it isn't in qemu). 3) fix the documentation (I started into that when I realized the By not pushing the fixes, we guarantee that nobody can use the feature, and thus will technically still be able to change the name of the attribute even after arelease has passed (because we won't break anyone's usable config).
