Apologies for my late reply we had a long holiday he= re.=C2=A0 To answer you: Yes the =C2=A0guest VM become completely frozen and non responsive as soon = as its disk has any activity for example when we shutdown or do a yum updat= e.=C2=A0 Versions of all the components involved - guest OS, host OS (qemu-kvm versi= on), how do you run the VM (vdsm log would be helpful here), exact storage = specification (1Gb or 10Gb link? What is the NFS version? What is it hosted= on? etc.)=C2=A0Y. Some facts about our environment: 1) Previously, this environment was using XEN using raw disk and we change = it to Ovirt (Ovirt were able to read the VMs's disks without any conversion= .)=C2=A02) The issue we are facing is not happening for any of the existing= VMs.=C2=A03) This issue only happens for new VMs.4) Guest (kernel v3.10) a= nd host(kernel v4.1) OSes are both CentOS 7 minimal installation.=C2=A05) N= FS version 4 and Using Ovirt 4.16)=C2=A0The network speed is 1 GB.7)=C2=A0T= he output for rpm -qa | grep qemu-kvm shows:=C2=A0 =C2=A0 =C2=A0qemu-kvm-co= mmon-ev-2.6.0-28.e17_3.6.1.x86_64 =C2=A0 =C2=A0 =C2=A0qemu-kvm-tools-ev-2.6.0-28.e17_3.6.1.x86_64=C2=A0 =C2= =A0 =C2=A0qemu-kvm-ev-2.6.0-28.e17_3.6.1.x86_648)=C2=A0The storage is from = a SAN device which is connected to the NFS server using fiber channel. So for example during shutdown also it froze and shows something like this = in event section: VM ILMU_WEB has been paused due to storage I/O problem.
