System: CentOS Linux release 6.0 (final) Kernel: 2.6.32-71.23.1.el6.x86_64 KVM: QEMU PC emulator version 0.12.1 (qemu-kvm-0.12.1.2) Libvirt: ibvirtd (libvirt) 0.8.1 Hi everyone, I only recently subscribed to this list and hope you can shed some light on the following error. I created a VM on my Centos 6 KVM machine, used a qcow2 image and wanted to create a snapshot via 'virsh

Attempting to take snapshots of VM using virsh with the following command, # virsh -c qemu:///system snapshot-create CentOS6-x86-001 Results in the following error, error: internal error unable to execute QEMU command 'savevm': The command savevm has not been found The VM's virtual disks are qcow2. Below is the XML file for this vm ------------ <domain type='kvm'

Hello, I am running into issues restoring VMs during reboot for some of my XP VMs - the environment is QEMU 2.2.0, libvirt 1.2.12 on CentOS 6.5 with KVM and libvirt-guests is set to suspend at shutdown. The weird part is Windows 7 is restored properly from the managedsave however XP does not, doing a start from virsh shows this: virsh # start xp-check error: Failed to start domain xp-check

It just doesn't work when

Hi, Is anyone clear about the format of qemu file for savevm or loadvm? bruce

Hello all: This seires is an update of last version of multiqueue support to add multiqueue capability to both tap and virtio-net. Some kinds of tap backends has (macvatp in linux) or would (tap) support multiqueue. In such kind of tap backend, each file descriptor of a tap is a qeueu and ioctls were prodived to attach an exist tap file descriptor to the tun/tap device. So the patch let qemu to

A lot of people in the security community, myself included, are interested in memory forensics these days. Virtualization is a natural fit with memory forensics because it allows one to get access to a guest's memory without having to introduce any extra software into the guest or otherwise interfere with it. Incident responders are particularly interested in getting memory dumps from

But you can, technically, edit the save file (not using virsh), change the name and uuid and restore it. But don't seek help when
