[libvirt] Non-contiguous NUMA cell numbers
by Andrea Bolognani 04 Jan '16

04 Jan '16

Hi all, libvirt currently doesn't allow you to configure a guest with something like <cpu> <topology sockets='2' cores='5' threads='8'/> <numa> <cell id='0' cpus='0-39' memory='1048576' unit='KiB'/> <cell id='16' cpus='40-79' memory='1048576' unit='KiB'/> </numa> </cpu> with the following error: XML error: Exactly one 'cell' element per guest NUMA cell allowed, non-contiguous ranges or ranges not starting from 0 are not allowed The error message is very specific about not allowing gaps in NUMA cell numbering; however, on the very same host, I have $ numactl --hard | head -1 available: 4 nodes (0-1,16-17) so gaps in numbering are definitely possible, at least on ppc64. Should we consider relaxing this requirement and allow arbitrarily-numbered NUMA cells? Is there a specific reason why it was forbidden in the first place? Cheers. -- Andrea Bolognani Software Engineer - Virtualization Team

[libvirt] [PATCH v8 0/5] Partial posting of updates to Add quorum to libvirt
by John Ferlan 04 Jan '16

04 Jan '16

I took a few cycles to reformat the initial 5 patches of the add quorum support posted as a v7 here: http://www.redhat.com/archives/libvir-list/2015-December/msg00119.html These patches are easily separable from the rest of the series. Rather than see things linger for months on end, trying to make small leaps. Changes in the series are to reorder things slightly, follow some of the review comments from previous series, and a few other things along the way. I've looked at this way too long to - hopefully I haven't missed anything. Most I forget... One I do remember is the virStorageSourceCopy changes in patch 5 where I believe the "Get" and "Set" wanted to use the 'i' index rather than having the "Get" use the 'i' and the "Set" always use '0'.

[libvirt] [PATCH] bhyve: bhyveload: respect boot dev and boot order
by Roman Bogorodskiy 02 Jan '16

02 Jan '16

Make bhyveload respect boot order as specified by os.boot section of the domain XML or by "boot order" for specific devices. As bhyve does not support a real boot order specification right now, it's just about choosing a single device to boot from. --- src/bhyve/bhyve_command.c | 49 ++++++++++++++++++++--

[libvirt] Proposal for snapshotting functions of volumes
by Wido den Hollander 25 Dec '15

25 Dec '15

Hi, Currently libvirt is lacking support for snapshotting volumes through the storage pool mechanism. I want to add this to libvirt, but since the internals and the API design ideas of libvirt are not fully known to me I wanted to put this up for a basic review first. This patch can also be viewed on Github: https://github.com/wido/libvirt/commit/4483ab247f607250c5b3314d0a19509ef251… My main questions are: * Is this something we would like to see in libvirt? * If so, am I on the right track? * If so, what API calls should be different? The steps I want to take: 1. Add the new API calls 2. Add support to the RBD backend 3. Add support to virsh 4. Add support to the Java bindings The Apache CloudStack project uses libvirt intensively and I want to add as much support to libvirt as we need so that we don't do stuff inside CloudStack where libvirt might be a lot better place to do it. Any comments are very much appreciated before I start spending hours of my time on this :) Wido

[libvirt] [PATCH] vz: BUG: fix connecting hang in case of init failure
by Maxim Nestratov 24 Dec '15

24 Dec '15

In case of prlsdkLoadDomains fails, vzOpenDefault should clear connection privateData pointer every time its memory is actually freed. Also it is not necessary to call vzConnectClose if a call to vzOpenDefault fails, because they both make cleanup of connection privateData.
