Hello,
I have Xen 3.0 running in my system. I have compiled a custom kernel
for the dom0 in order to have support for megaraid (my root filesystem
is in a megaraid radi) and USB (I have an usb cdrom). In the dom0 I can
mount and umount the cd without any problem.
So now I want to be able to mount the CD in the domU. So, for one of my
domU''s I change:
disk = [''file:/vhosts/images/root_base.img,hda1,w'',
''file:/vhosts/images/swap_base.img,hda2,w''
]
for:
disk = [''file:/vhosts/images/root_base.img,hda1,w'',
''file:/vhosts/images/swap_base.img,hda2,w'',
''phy:scd0,hdc,w''
]
(scd0 is my cdrom device)
but it doesn''t working. Every time I boot this domU, I get the error:
general protection fault: 0000 [#1]

<7>vif3.0: no IPv6 routers present
although I get the error, the domU seems to be booted. I can connect to
it and so on. The problem is:
* If I disconnect from its console, I can''t connect to the console
anymore. I even can''t connect to any other console.
* I can''t shutdown the system. If I try it, the domU becomes zombie and
I can''t destroy it. I can''t destroy any other domU too.
Any idea?
