Hello,
I've used virt-install + kickstart to setup machine. Then I've moved the
script to a production machine and in the guest the disk was not 'vda' but
'sda', how is this done?
There are differencet vesrions of libvirt between my fedora (tesing system)
and gentoo (production system).

Naming depends on the driver. You only get vda when using the standard
virtio driver.

New subject: [libvirt-users] Can LXC and KVM run in a single node at the same time? How does LXC vcpu map to cgroups cpu.shares?
hi,all
I want to run LXC and KVM in a single node at the same time. Is it possible?
If so, can resource isolation work properly? that is, can LXC and KVM get their
corresponding shares of resources(vcpu, memeory, etc..)?
In that case, how does LXC vcpu map to cgroups cpu.shares?
many thanks!

Yes, you can have both hypervisor drivers running on the same machine;
you choose which hypervisor you connect to according to the URI that you
pass to 'virsh -c' or virConnectOpen().

Yes, both LXC and qemu hypervisors know how to limit guest resources
using cgroups under the hood; in particular, see
http://libvirt.org/formatdomain.html#elementsCPUTuning for the XML to
use. <cputune> has a sub-element <shares> that maps nicely to the
cgroups cpu.shares.
