Xen users - Mar 2006 - Swap not mounting!

Hi,

I just discovered that none of my VMs does not mount the swap drive!
The VM just does not "see" the /dev/sda2 as a block device.

It seams it doesn't matter if the supplyed drive is phy or file.

It seams a few people had this problem in the past, but noone posted
the solution. Can anyone point me into the right direction?

Best regards,
Uros

PS: my config:
kernel = "/boot/vmlinuz-2.6-xenU"
memory = 128
name = "slack"
vcpus = 1
vif = ['']
#dhcp = "dhcp"
dhcp = "192.168.1.151"
netmask = "255.255.255.0"
hostname = "slack"
disk = [ 'file:/opt/xen/domains/slack/slackware.10-2.img,sda1,w',
'psy:/dev/evms/Swap,sda2,w' ]
root = "/dev/sda1 ro"

or with

disk = [ 'file:/opt/xen/domains/slack/slackware.10-2.img,sda1,w',
'file:/opt/xen/domains/slack/slackware.swap,sda2,w' ]

Did you marked them as swap, with mkswap?

Have you included a swap entry in your /etc/fstab?

/dev/sda2    swap   swap    defaults   0 0

Hope that helps,

UT> ''psy:/dev/evms/Swap,sda2,w'' ]
     ^^^

Shouldn''t this be ''phy'' instead of
''psy''?

Verify that you have udev and hotplug installed.

Sorry for sending a misleading Subject in the last email.

[As I was writing a long and detailed problem report I suddenly
realized that the hotplug system was the culprit, and short thereafter
solved the problem (when using Debian). And I accidently didn''t change
back the subject, which I changed in the first place to signify a
concurring problem report.]
