Public bug reported:
Hi,
I am using virt-manager for testing live migration. Two machines having
IPs 192.168.2.250 and 192.168.2.48 has been used.
Software versions:
#kvm -verion
QEMU emulator version 0.14.1 (qemu-kvm-0.14.1), Copyright (c) 2003-2008 Fabrice
Bellard
#uname -r
3.0.0-12-generic
I am running a VM in 192.168.2.250 machine and trying to migrate to
192.168.2.48. The other configuration details are given below.
System with IP = 192.168.2.250 is nfs-kernel-server is running
#cat /etc/exports
/var/lib/libvirt/images
192.168.2.250/255.255.255.0(rw,sync,fsid=0,no_root_squash)
System with IP = 192.168.2.48 is mounted with shared
#cat /etc/fstab
192.168.2.250:/var/lib/libvirt/images /var/lib/libvirt/images nfs
defaults 0 0
#df -k
192.168.2.250:/var/lib/libvirt/images 49886464 24680448 117592064 18%
/var/lib/libvirt/images
But after this when I try to migrate I am getting below error
Unable to migrate guest: operation failed: migration to 'tcp:System-2' failed:
migration failed
