Partition Scheme

Partition Size Description
/ 80-100 GB Root partition containing all Hardware Node operating system files, OS templates and ISOs
SWAP 4 GB + Paging partition for the Linux operating system(Swap memory is been used by virtual servers if there is shortage of real memory)
LVG (Volume Group) All the remaining space on the hard disk This partition will be used to create Logical Volumes that will act as the VPS (DomUs) storage.

NOTE : You must NOT create any Logical Volume and MOUNT it. This must be an EMPTY VOLUME GROUP.
Virtualizor will not delete any pre-existing LVs in the Volume Group. But its recommended to have an empty Volume Group.

Virtualizor Network in KVM

Virtualizor will create a viifbr0 bridge.
viifbr0 detects the IP, Netmask, GATEWAY from :

/etc/sysconfig/network-scripts/ifcfg-eth0

Hence if you change the above file, you will need to restart the virtualizor network :

root> service virtnetwork restart

Start Command :

root> service virtnetwork start

Stop Command :

root> service virtnetwork stop

Trouble Shoot

NOTE : In all cases please remember to disable SElinux. The Virtualizor installer will try to disable it. For KVM make sure that VT is enabled from bios so VPS can be able to started .

Cant open http://IP-Address:4084

Please check if your iptables firewall is running You can disable it with the following command :

root> service iptables stop
