[libvirt-users] libvirt-clone - Slow image cloning on a Server

[Philip Banh]

Hello there,

I have libvirt/kvm installed on a HP DL380 server and it seems to be cloning a template image very slowly, in fact a 50GB image just doesn't gets stuck after 7%. Is there a reason why this might be happening? I've tried the same setup on a desktop and never had this issue. The command and setup is listed below:

virt-clone -o template.img -n new-clone -f .../new-clone.img

System

-          12 cores, 32 GB of memory

-          Running CentOS 7

-          XFS file system using LVM

-          Libvirt 1.2.17
Thanks,
Philip
