[Users] VM Pausing with Storage IO errors

[Dafna Ron]

you can look at the vm qemu log and libvirt to get more info.
/var/log/libvirtd.log and /var/log/libvirt/qemu/<vm_name>.log

also, if the vm is pausing right after it's starts, in the vds that the 
vm is run on, right after the libvirt xml is logged you can probably see 
a reason why the vm is paused

you can attach all logs (engine, vdsm logs from spm and the host the vm 
is running on, libvirtd log and vm qemu log) and send to the list and 
I'll go through them to see if I can see anything.
