Libvirt Virtualization Problem
Dear Sir/Madam:
I use virt-manager to create a new virtual machine(it's name is generic), then I edit generic to set it's cpu_mode as 'host-model', and I start it, but when dumpxml generic, it's cpu_mode is changed as 'custom'.
I want to know that why it is?
And what's the principle of dumpxml?
Thanks!

Nested KVM issue
...compute VM.
Please, post
1) # virsh dumpxml VM-L1 ( where on L1 level you expect nested KVM to appear)
2) Login into VM-L1 and run :-
# lsmod | grep kvm
3) I need outputs from VM-L1 ( in case it is Compute Node )
# cat /etc/nova/nova.conf | grep virt_type
# cat /etc/nova/nova.conf | grep cpu_mode
Boris.
The only workaround now is to shutdown the compute VM and start it back from baremetal with virsh start.
A simple restart of the compute node doesn't help. It looks like the qemu-kvm process corresponding to the compute VM is the problem.

Nested KVM issue
Hello,
I have an OpenStack setup in virtual environment on CentOS 7.
The baremetal has *nested KVM* enabled and 1 compute node as a VM.
Inside the compute node I have multiple VMs running.
After about every 3 days the VMs get inaccessible and the compute node
reports high CPU usage. The qemu-kvm process for each VM inside the compute
node reports full CPU usage.
Please help me with some hints

xenoprof patch for oprofile-0.9.7
I am rebasing Fedora rawhide oprofile package to oprofile-0.9.7. The xenoprof patches on http://xenoprof.sourceforge.net/#download look a bit dated. The newest version is for oprofile-0.9.5.
I massaged the patch oprofile-0.9.5-xen.patch to apply to oprofile-.0.9.7. Attached is that updated patch. Does this look reasonable? Is there a desire to get this into upstream oprofile? Or should the
