Hello
I found a workaround to that pb of vzmigrate VM: PRL_ERR_READ_XML_CONTENT
I virsh edit the VM and changed multiple parameters with no success,
then with change in graphics vnc parameters it became possible to
migrate again ! now I have:
<graphics type='vnc' port='-1' autoport='yes' websocket='-1'
listen='::1' passwd='secret'>
autoport was set to "no" and a static portnumber was set
Now that I can migrate the VM , I am still stuck in another pb , that VM
that has a hda drive on an IDE controler, cannot start on a VZ host ,
but can on another one [1] and can always with virsh start !?
/[root@olymp qemu]# prlctl start eonimte//
//Starting the VM...//
//Failed to start the VM: Operation failed. Failed to execute the
operation. (Details: unsupported configuration: Only scsi disk supports
vendor and product)//
//[root@olymp qemu]# uname -a //
//Linux olymp.int.fr 3.10.0-862.20.2.vz7.73.29 #1 SMP Thu Feb 21
17:35:43 MSK 2019 x86_64 x86_64 x86_64 GNU/Linux/
I am still searching why .
If you have any idea why IDE disk cannot be started by prlctl command !?
it can be started with KVM virsh start though !
thanks for your help .
regards .
PS [1] where IDE drive works is on: qemu-kvm-vz-2.10.0-21.7.vz7.67.x86_64
where it doesn't : qemu-kvm-vz-2.12.0-18.6.3.vz7.21.6.x86_64

Hello
I cannot migrate a VM from one host to another, it fails with

here are the details :

I must admit that I did edit the VM definition with virsh edit in
order to specify a different disk name (created from another KVM only
machine)
My initial concern is to convert a KVM machine to virtuozzo prlctl
management tools, so I clone an existing virtuozzo VM and changed it's
disk image name to the one's of the KVM only image:
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source
file='*/vz/vmprivate/60d7f6ed-bfa0-40d4-8bc2-c5a705ebb553/eonimtevIDE.qcow2'*/>
<target dev='hda' bus='ide'/>
<boot order='1'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
[root@server2 ~]# ls -al /etc/libvirt/qemu/
total 28
drwx------ 3 root root 4096 6 août 23:35 .
drwx------ 5 root root 4096 6 août 22:44 ..
-rw------- 1 root root 4685 6 août 23:35 eonimtev.xml
1) What is wrong with this VM: PRL_ERR_READ_XML_CONTENT ?
2) Is there a way to "register" to virtuozzo a KVM VM by copying it's
/etc/libvirt/qemu/vm.xml and disk image to a
'*/vz/vmprivate/$uuidgen/*hardisk.hdd
somthing like prlctl register $uuidgen vmname ... ?
thanks .
