Hi,
I'm trying to figure out if libvirt supports a domain rename
feature, like xen's "xm rename" command. I couldn't find anything in
the docs suggesting such a function. Am I missing something?
Thanks!

I have had no success using bootloader_args for anything, under Xen PV

Hi!
Occasionally of late, I've seen a few cases where libvirtd cpu usage
shoots up to 100% and stays there indefinitely. This seems to happen
when a QEMU VM is starting up, although on one occasion I *think* I
saw it happen after a QEMU VM was p2p-migrated.

This in itself was going to be a problem, because I hand-compiled

Hi,
I am running libvirt 0.8.6 on qemu (kvm, really) 0.12.5. I have
noticed that while a live migration is running, I cannot do anything
else with libvirt -- even 'virsh list' blocks without output until
the migration is almost done.

I would like to use the virDomainMigrateSetMaxDowntime but I'm a bit
confused about how to use it.
If I try to set the downtime before I call domain.migrate(), I get the
error "domain is not being migrated". But I cannot call it afterwards
because domain.migrate() does not return until the migrati

the problem is not that domain.migration will not return till it's
finished. that makes perfect sense and is totally fine.
the problem is that i can't seem to do ANYTHING els

yup -- when i start my migration using my python application, 'virsh

I still had a box around where I was using a hand-compiled libvirt with

Just to make sure that my strange compiling/packages aren't causing the
problem, I've set up two servers running fedora 14 with the official
libvirt packages. i experience the same proble

Hey John,
If I understand correctly, you are trying to get access to the
character device after you've created the domain. The exact device
is auto-assigned when the VM is created, but you can get the correct
device from the domain XML after the domain is running.
hi,
i tried to add a 'cache' argument to the 'driver' element in my
domainxml for qemu/kvm. i tried adding cache="none" as well as
"writethrough" and "writeback", but every time i get these errors:

yup, that was the exact culprit -- /vms is a FUSE-mounted FS which
doesn't support O_DIRECT. t
Arpita,
I have used the python bindings extensively, but AFAIK there is no
documentation specifically for python. The python bindings closely
follow the C API, which is documented here:
http://libvirt.org/html/libvirt-libvirt.html
The function names in pyt
ss, although it seems as though actual migrations have gotten much
faster.
just an fyi.

As eblake mentioned on the other mailing list, you have to have an ACPI
daemon listening for ACPI events in the guest in order for 'virsh
shutdown' or 'virsh reboot' to do anything. If the guest or the ACPI
daemon crash, 'virsh shutdown' won't work.
In my own code, I set a timeout of a minute to l

i've reported this issue before, so i guess this is a regression. looks
like the python bindings for 0.9.3 are leaking file descriptors:

Hi!
I'm comparing the cpu usage of a VM from virDomainGetInfo and the
usages returned per-vcpu from virDomainGetVcpus and the totals do
not match up.
I expect that the cpu usages reported per-vcpu, when summed, should
equal the total cpu usage of the domai
