Hello, there,
I have been following the howto from
http://fedoraproject.org/wiki/FedoraCore5XenQuickstart on Fedora Core
5 Test 2.
in my grub.conf I added init 3, but each time it reboots my machine.
So i followed the rest of the tutorial in init 5.
I have even replace all sda1 by hda1 when applicable since my fdisk -l is
[root@goorah ~]# fdisk -l
Disk /dev/hda: 40.0 GB, 40060403712 bytes
255 heads, 63 sectors/track, 4870 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 132 4870 38066017+ 83 Linux
/dev/hda2 1 131 1052226 82 Linux swap / Solaris
Otherwise I did (i think) everything.
If I do xm create -c fedora-guest1, It will end each time with:
awk: cmd. line:1: fatal: cannot open file `/proc/mounts'' for reading
(No such file or directory)

do it have to do with the replacement of sda1 with hda1 ?

Because:> > cat: /proc/cmdline: No such file or directory> > mount: mount point /dev/pts does not existYou might also be missing an empty /dev directory. Try mounting your guest system and create those two directories if they are missing: mkdir x mount -o loop yourguest.img x (not sure if the new xenguest.py creates a partition or a disk. I am not sure how to mount partitions within a disk image) ls x and if they do not exist: mkdir x/dev x/proc umount x And try again. Paul

If you pretend with either IDE or SCSI, the xen block driver does heinous things with stealing block majors and I wouldn''t expect this support to stay as some of the Xen drivers start to move upstream Jeremy Jeremy
