I tried to bind libvirt to those IP-Range but after that the livemigration doesn't wor...

The panic point is inside ap_suspend(): .... while (info->do_spin) { cpu_relax(); read_lock(&suspend_lock); HYPERVISOR_yield(); ----> guest might panic on the invocation of this function....

hello everybody and happy new year! I am a newbie in libvirt use, and I use it mostrly throught OpenNebula. Anyway, I noticed that one of the nodes can be a destination of a livemigrate but not the source. This is the environment: 4 blades nicknamed(*) red3, red9, red10, red11, each with 8 Intel E5506 cores (@ 2.13GHz) running CentOS 5 and KVM as hyoervisor.

I have several systems running 64bit SLES11SP1. I''m trying to Live Migrate between a couple of them and it''s not working, although the same VM will run on each one starting it manually. The system are not identical. Would one expect migration to work between these two systems? See below. Thanks, James The first system is a ProLiant DL360 G6: Proc 1:2533 MHz Execution

I am virtualizating Samba 4.1.14 with vmware free. Any of you already virtualized and had used vmconverter server to copy a PDC already working with a domain ? Can I copy the hole machine with VMCONVERTER without any problem. I had done already this procedure with a laptop to another place and worked very well. This is pratical and easy, but is this procedure recommended? I would like any advise

Hello, I am trying to run a virtual machine with qemu-kvm and libvirt as a user.
