[one-users] Migrate error with OpenNebula 3.4.1 using KVM hypervisor on Ubuntu 12.05 box

[Duverne, Cyrille]

Hello Thai,

Looks like the ownership of disk.1 isn't correct, this might be due to
bad "dynamic_ownership" config in "/etc/libvirt/qemu.conf".

Could you run : "sudo cat /etc/libvirt/qemu.conf | grep ownership"
If you get dynamic_ownership=1 , please edit the file and set it to 0

To gain access on the disk.1 of your VM, run : "sudo chown
oneadmin:oneadmin /var/lib/one/var//datastores/0/8/disk.1"

And try to livemigrate your VM again, and try to create a new one and
livemigrate it as well.

Hope you'll fix your issue.
Kind regards
Cyrille

Dear Cyrlle,

Thanks for your support.

According to your metions, here is the output I got out:

oneadmin at OneVMHost:~/var/11$ ls -lArth
/var/lib/one/var//datastores/0/8/disk.1
-rw-rw---- 1 libvirt-qemu kvm 370K Sep 26 00:12
/var/lib/one/var//datastores/0/8/disk.1

oneadmin at OneVMHost:~/var/11$ cat /etc/group |grep oneadmin
root:x:0:oneadmin
oneadmin:x:10000:oneadmin
kvm:x:110:oneadmin
libvirtd:x:111:thaibinhtt,oneadmin
oneadmin at OneVMHost:~/var/11$

Hello Thai,

Could you give the output of : ls
-lArth /var/lib/one/var//datastores/0/8/disk.1 ?
Another thought : Is "oneadmin" part of the "libvirt" group ?

Dear,

I am trying to live migrate from KVM host to another KVM host but I
always catch an error message which I quote below. Does anyone know
the reason and how to solve this problem ?
