virt-p2v - Windows 10 guest hangs at boot after successful P2V
Hi all,
I successfully virt-p2v'ed a Windows 10 laptop to my Centos 7.3 instance
running KVM. However, on boot, the guest hangs. Is there a registry fix
that is needed after the P2V is done? Here is what is in the guest's

Start domain with usable QMP connection?
Is there any way to get virsh / libvirt to create a domain such that I
can later connect to it via QMP (without hacking the code)?
The command line that libvirt creates for my current setup looks like this:
/usr/local/bin/qemu-system-x86_64 -S -M pc-0.12 -enable-kvm -m 512
-smp 1,sockets=1,cores=1,threads=1 -name winxpsp2 -uuid

I wanted to add “-qmp tcp:127.0.0.1:1235” when creating VM because I was using a multi-level debugger which needs this option to get more information of the VM

Is there a way to disable libvirt qemu monitor while creating kvm vm using virsh?
Hi,
Now for some reason, I need to add “ -qmp tcp:127.0.0.1:1235” when creating a KVM VM using libvirt. This command meaning in “qemu-kvm --help” is: -qmp dev like -monitor but opens in 'control' mode.
I added command-line equivalent options into the xml file, like below format:

Unexplained shutdown of VM on upgrade of libvirt package
I am running KVM on Centos 6.3 and am seeing an unexplained shut down of
two guests. The libvirt package was upgraded to
libvirt-0.10.2-18.el6_4.4.x86_64 at the time of the shutdown. Only the
two guests shown below was affected, while 9 others running on the same
hypervisor were not.
Can some one help me to find the cause please ?

Libvirt guest can't boot up when use ceph as storage backend with Selinux enabled
Hi there,
I met one problem that guest fail to boot up when Selinux is enabled with guest storage
based on ceph. However, I can boot the guest with qemu directly. I also can boot it up
with Selinux disabled. Not sure it is a libvirt bug or wrong use case.
