When trying to create a new domain I get the following error:
root@chekov:~# xm create vmid=1
Using config file /etc/xen/xmdefaults
Error: Error creating domain: [Failure instance:
Traceback:xen.xend.XendDomainInfo.VmError, vbd: Segments not
foundXXXXXX:uname=phy:hda3
If I do a dry-run:
root@chekov:~# xm create -n vmid=1
Using config file xmdefaults
(vm
(name ''This is VM 1'')
(memory ''64'')
(cpu ''1'')
(image
(linux
(kernel /boot/vmlinuz-2.4.26-xenU)
(ip :1.2.3.4::::eth0:dhcp)
(root ''/dev/sda1 ro'')
)
)
(device (vbd (uname phy:hda3) (dev sda1) (mode w)))
(device (vbd (uname phy:hda4) (dev sda2) (mode w)))
(device (vif (mac aa:0:0:2e:29:6c)))
)
I have created a Slackware filesystem pretty much the same way I used to do
under UML, the most important steps are shown below:
# I have created 2 partitions for my guest os, hda3 and hda4
root@chekov:~# fdisk -l /dev/hda
Disk /dev/hda: 8455 MB, 8455200768 bytes
255 heads, 63 sectors/track, 1027 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 697 5598621 83 Linux
/dev/hda2 698 742 361462+ 82 Linux swap
/dev/hda3 743 865 987997+ 83 Linux
/dev/hda4 866 882 136552+ 82 Linux swap
# I created filesystems on both of them:
root@chekov:~# mkfs -t ext3 /dev/hda3
root@chekov:~# mkswap /dev/hda4
# I mounted my new guest root filesystem:
root@chekov:~# mount /dev/hda3 /build/root
# I edited all the tagfiles so they only had ADD or SKP selections and
installed my choice of packages:
root@chekov:/build/slackware# /sbin/installpkg -root /build/root a/*.tgz
ap/*.tgz d/*.tgz l/*.tgz n/*.tgz
# I created a new fstab:
/dev/sda1 / ext3 defaults 1 1
/dev/sda2 swap swap defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0
# And finally, I unmounted /dev/hda3 before trying to create the new domain
Any help is appreciated,
Fredrik Dahlberg
