Hi, I just tried to migrate a VM from one machine to another. The basics work - after a "xm migrate <VM> <destination> - the VM is up and running on the 2nd machine. But... the network port doesn''t come up. Trying an ifup eth0, or even a /etc/init.d/networking/restart, gives the following (virtual) console error: test_2:/home/milesf# /etc/init.d/networking restart Reconfiguring network interfaces...milesf[1667]: ERROR: Interface eth0 does not seem to be present in the system SIOCSIFADDR: No such device eth0: ERROR while getting interface flags: No such device SIOCSIFNETMASK: No such device SIOCSIFBRDADDR: No such device eth0: ERROR while getting interface flags: No such device eth0: ERROR while getting interface flags: No such device Failed to bring up eth0. The only way to get networking back up is to reboot the VM. Any ideas? Thanks, Miles Fidelman -- In theory, there is no difference between theory and practice. In<fnord> practice, there is. ....

[Xen-users] Re: networking doesn''t work after migrate - FIXED (oops)
Silly me. Seems like I forgot to restart xend after fixing a typo in the config file on the 2nd machine. Sorry about that.
