Subject: NFS boot : Is it a bug?
Hi
I am trying migration and there are few observations. One of them seem to be a
bug but i am not too sure... I may mention that migration is working on my
machine but its not the way it was supposed to be.
1- I have set up the migration through NFS. Now in the config file of xen guest
say mvd1.cfg i have set up the config as pasted
#NFS options
nfs_server=''192.168.0.10''
nfs_root=''/nfs/xen-mig/mvd1''
root= ''/dev/nfs''
The thing is that commandline argument passed does not specify root=/dev/nfs to
the guest kernel. I can see during the boot the commandline is missing
root=/dev/nfs thing. So the
domain does not boot correctly. I am required to force this by adding
extra=''root=/dev/nfs'' to make it work. Is it a bug? or am i
missing something.
I am using Xen 3.0.1 and have compiled it from source. Once i do this the
domains boot from the NFS and work the way they are required to do.
2- Another thing is that once i pin (export) the NIC to guest domain with
pciback ... the domain works, but upon migration it crashes for obvious reasons
that it cannot find the same PCI address. Is there anyway to export a PCI (NIC
in my case) to migrating guest domain?
Any help would be appreciated.. thanks in advance.
Best Regards,
Muhammad Atif
