Create the LVM2 logical volume of size 256 MB:

# lvm lvcreate VolGroup00 -n LogVol02 -L 256M
Format the new swap space:

# mkswap /dev/VolGroup00/LogVol02
Add the following entry to the /etc/fstab file:

/dev/VolGroup00/LogVol02 swap swap defaults 0 0
Enable the extended logical volume:

# swapon -va
Test that the logical volume has been extended properly:

# cat /proc/swaps # free

Some of the default HyperVM templates have an issue with nash-hotplug taking a large amount of resources (usually 99%). If you are having this issue, a quick an easy way to fix this is add the following to /etc/rc.local on the guest VDS:

pkill -9 nash

This is a temporary fix, until a more permanent one is provided by Lxlabs/HyperVM. This problem is supposedly already fixed in CentOS 4, however seems to still appear in Debian 3. For debian, do the following:

Open up /etc/init.d/local and add:

#!/bin/bash
pkill -9 nash

Then run the following:

chmod 755 /etc/init.d/local

Error Message : Starting OpenBSD Secure Shell server: sshdPRNG is not seeded

How to fix
#cd /dev ; ./MAKEDEV urandom ; /etc/init.d/ssh start

ขอบคุณน้องแจค แห่ง tanoy.net

#cd /boot
#mkinitrd --omit-scsi-modules --with=xennet --with=xenblk --preload=xenblk my-initrd $(uname -r)

Error ที่เจอก็จะหายไปในทันที
