[Xen-users] VFS: Cannot open root device "sda1" or unknown-block(0, 0) -- in domU
Hello again, My kernel is correct, and it''s always been correct. This error only happens if I start two or more VMs in quick sucession. If I wait a short while (i.e. time to figure out why a VM started then died) and try again, it''s fine. For testing purposes I''m using loopback files, 2 for each VM (1 filesystem, 1 swap). -- Mike Williams System Administration Manager - Comodo Office Tel Europe: +44 (0) 161 8747070 Fax Europe: +44 (0) 161 8771767 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Try renaming it to xvda1 in your fstab and domU config. -- Christopher G.

What major and minor are they supposed to be?
