We have the following test environment: 2 x CentOS 5.5 KVM virtual hosts 2 x CentOS 5.5 network storage boxes with NFS shares on LVs on DRBD (primary/secondary, no HA, just replication). We have installed both CentOS and Win7 guests which live migrate almost instantly between hosts using Virt Manager (or virsh migrate). The problem is that the guests does not retain their running state after migration, but instead arrive on the new host in "reboot after unclean shutdown" state. The migrated machines also lose IP connectivity (static IP) upon migration to new host, but regain it on migration back to original host. So, live migration in this case isn't producing the expected results (a running, usable guest). Same results using "migrate offline" option and pausing machines before migration. Any pointers on what we're doing wrong? Is there a need for us to implement hook scripts? Michael Hall IT Communications Officer Alice Springs Town Council mhall@xxxxxxxxxxxxxx (08) 8950 0561
