[et-mgmt-tools] virt-p2v 0.9.7 - temporary failure in name resolution

[Henry Kemp]

I've just run through the process of getting virt-p2v setup to PXE boot
and that seemed pretty straightforward. During the install though it
didn't set up name resolution correctly - I'm assuming it should try to
do this from either looking at the files from the guest its trying to
virtualise or through DHCP?

Working throgh the virt-p2v script from the source code and the output
of virt-p2v (below) it looks as though it mounts up /etc from the
original host correctly and /etc/resolv.conf looks ok.

Then because this client is using DHCP when we run "/etc/init.d/network
start" it tries to move resolv.conf to one side but it can't because the
filesystem has been mounted ro. The script then unmounts /etc and we go
back to the /etc filesystem from the live image which doesn't have
anything setup for resolv.conf.

I can get around this by entering the IP of the target Xen host but it
would be a bit more user friendly if it picked up resolv.conf from the
box we're trying to virtualise.

Rgds,

Henry
