[Xen-users] NFS boot : Is it a bug?

[Muhammad Atif <m_atif_s@xxxxxxxxx>]

 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
