I'm using a KVM hypervisor on a Ubuntu Server 12.04 server. My virtual machine's virtual disks are LVM volumes, formatted as ext3. The guest OSes are all Ubuntu 12.04 and 14.04 server.
Everything runs smoothly, except that the virtual machines gets stuck during boot, displaying a message like :
fsck from util-linux 2.20.1 /dev/vda1: clean, 260102/6340608 files, 1323923/25337600 blocks
This happens whether the VMs have been rebooted/shat down through normal shell commands or "virsh-destroy"ed. I have to reboot them between 1 and more than 15 times to get them to boot all the way.
When I have to reboot them more than once, the counter one the above message are slightly increased at each reboot.
I have the same issue with another KVM server with a similar setup.
What could cause such a problem and how would I fix it ?
- The server has a raid 6 array of 6 2To disks
- All the VMs and LVs have been created through virt-manager
- The filesystem used on both the hypervisor and the VMs is ext4
