[Xen-devel] How does pvops create loop device for initrd to support Xen live image?
Hi,
I want to create a Xen live image based on fedora project
(http://fedoraproject.org/wiki/FedoraLiveCD/USBHowTo).
Since the root fs is packed as a squashfs image, initrd will have script to
mount it and switch root into it.
But now I get the errors after booting up xen and pvops. (see log attached)
It complains pvops is not aware of any loop device. I compile pvops with
BLK_DEV_LOOP=y.
...
losetup: Could not find any loop device. Maybe this kernel does not know
about the loop device? (If so, recompile or `modprobe loop''.)
loop: can''t get info on device /osmin.img: Inappropriate ioctl for
device
Usage: mount -V : print version
mount -h : print this help
mount : list mounted filesystems
mount -l : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere''.
...
Thanks.
Shane

For sure, that''s your problem, you must correct the kernel modules version...
