Hi list,
I want to use the centos kernel-xen in a centos 5.2 environment but I
cannot boot because the kernel shows:
VFS: Cannot open root device "xvda1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
However, the initrd has definitely the drivers for xennet and xenblk
(I unpacked ans looked inside) but while booting, there are no devices
recognised.
my Corresponding files are attached.
Hope that somebody can help me...
Ralf
