Domain-0 Memory
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.
For RHEL & CentOS < 7
iptables -I INPUT 2 -p tcp -m tcp --dport 5900:6000 -j ACCEPT
For RHEL & CentOS 7+
firewall-cmd --zone=public --permanent --add-port=5900-6000/tcp
firewall-cmd --reload
Trouble Shoot
Cant open http://IP-Address:4084
Please check if your iptables firewall is running You can disable it with the following command if even after allowing ports, the panel is not working :
For CentOS 7 :
Server boot issues
If the server hangs on a black screen with a blinking prompt then you can use this guide :
Booted into wrong kernel
If you get the error as booted into wrong kernel after fresh installation.
Go to Admin Panel -> Configuration -> Slave Settings -> Enable "Use XL" setting and Save the configuration. It should resolve the issue of booted into wrong kernel.
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 :
Note : The above command will restart the server's entire network.
