Hi,

VFS: Cannot open root device "sda1" 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)

to solve this you may install a "xen"-kernel ( linux-image-2.6-xen* ) or change "sda" to "xvda" ( http://wiki.xensource.com/xenwiki/Kernel.org_Linux_on_Xen )

Fabian


My experience is that either "sda" or "xvda" work in redhat 5-like domU's
but for redhat 4-like domU's you have to use xvda (that is, when dom0 is also redhat5-like). Is there any reason
why that would be?
