Before creating any VMs, its necessary to define your storage.
Navigate to Virtualizor Admin Panel -> Storage -> Add Storage
You will see the following wizard :
Fill in the details and define the storage.
It is very important that you set the Domain-0 (Hardware Node) memory in the GRUB so that there is no memory balloning of Domain-0 causing a lack of RAM for the virtaul servers. You can do that by editing /etc/grub.conf and adding dom0_mem=512M. An example is as follows :
title CentOS (2.6.18-194.26.1.el5xen) root (hd0,0) kernel /boot/xen.gz-2.6.18-194.26.1.el5 dom0_mem=512M module /boot/vmlinuz-2.6.18-194.26.1.el5xen ro root=LABEL=/1 module /boot/initrd-2.6.18-194.26.1.el5xen.img
You can also set the memory anytime :
xm mem-set Domain-0 512
Virtualizor uses ports from 4081 – 4085. If there is any firewall restricting this, you will need to allow these ports.
NOTE : In all cases please remember to disable SElinux. The Virtualizor installer will try to disable it. For xen HVM make sure VT is enabled from the bios or you will not be able to see HVM check Box .
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
Virtualizor Network in XEN ubuntu
Virtualizor will create a viifbr0 bridge.
viifbr0 detects the IP, Netmask, GATEWAY from interface eth0 is default. You can change it from configuration from admin panel as per your requirement:
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
