  • HVM is hardware and faster
  • PV is Paravirtualization and usually slower

Notes

Debian

Xen Config File: /etc/xen/xend-config.sxp

Install

apt-get install xen-linux-system
apt-get install xen-qemu-dm-4.0
dpkg-divert --divert /etc/grub.d/08_linux_xen --rename /etc/grub.d/20_linux_xen
update-grub

May want to do this eventually to limit dom0 ram: 

/etc/default/grub
# Xen boot parameters for all Xen boots
GRUB_CMDLINE_XEN="dom0_mem=1024M"

then 

update-grub

then edit 

/etc/xen/xend-config.sxp
(dom0-min-mem 1024)
(enable-dom0-ballooning no)

You would then need to reboot.

Network Scripts

/etc/xen/scripts/network-bridge
/etc/xen/scripts/vif-bridge

Notes

Configure

Debian wiki states that the network control scripts that come with Xen are going to be phased out eventually. Goes on to say that you should setup networking yourself.

Note: You need to zero out your eth0 connection or the bridge will disable eth0.

Something like: 

ifconfig eth0 0.0.0.0

aptitude install bridge-utils
brctl addbr br0
  • br0 could be anything like: whatever0
ip addr show
  • Just to see interfaces

You now need to add interfaces to the bridge 

brctl addif br0 eth0 eth1

To make the bridge perm you need to edit /etc/network/interfaces 

 /etc/network/interfaces 
 Template error: are you trying to use the = sign? Visit Help:Template#Escape template-breaking characters for workarounds.

or something using ethernet aliases: 

 /etc/network/interfaces 
 Template error: are you trying to use the = sign? Visit Help:Template#Escape template-breaking characters for workarounds.

You then need to edit /etc/xen/xend-config.sxp

Notes

HyperVM Free and looks like a great product. Does not work with CentOS 6 because CentOS dropped Xen?
  • Xen XCP
  • OpenVZ
  • Virtuzzo
  • ProxMox
  • SolusVM
  • vePortal


Most of these can integrate with a billing platform.

  • lxcenter.org

kloxo
