Admin Panel

After you login, you will see the Admin Panel Dashboard :



Virtualizor uses ports from 4081 - 4085.

If there is any firewall restricting this, you will need to allow these ports.


1. Input correct Proxmox Server Name and password in Configuration->Slave settings before trying to create vps/add storage.
You can find Proxmox Server Name in pvesh get nodes command output on your server.
2. NAT Pool is not supported for Proxmox.
3. Set the same storage path and name on Virtualizor panel to avoid create vps and import vps issues. 

Proxmox 7 Login Issue

If you are using proxmox 7 and facing virtualizor login issue then follow this steps:
1. SSH to your server and execute the following command

nano /etc/pam.d/common-password

2. Look for "password        [success=1 default=ignore] obscure yescrypt" line

3. Change the yescrypt in above line to sha512

4. Change the server password and try to login into virtualizor again

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 :

root> service iptables stop
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 start.

Error : The storage doesn't exist

If you get this error while adding Storage, please execute the following command :

root> vgchange -ay

Disk resize issue on Ubuntu 16 and Ubuntu 18

For vps hostname/disk resize issues on Proxmox 7 with sfdisk version 2.36+ , follow these steps to downgrade sfdisk on the server :

mv /sbin/sfdisk /sbin/sfdisk_new

wget -O /sbin/sfdisk

chmod 755 /sbin/sfdisk

HA / live mirgration

If you are using HA on Proxmox cluster or attempting Live migration from Proxmox panel then it will need certain pre-configurations made so that it updates the VPS on correct server on Virtualizor panel.

is_cloud should be used (set it to 1) when HA cluster is configured using Proxmox panel and Virtualizor panel is installed on those servers.

No need to use HA on the Virtualizor panel in that case.
is_cloud can be found in /usr/local/virtualizor/universal.php file on Virtualizor Master server 
assuming Master is Virtualizor Proxmox server too (should also be a part of the same cluster on Proxmox server)

2. Storage on Virtualizor panel needs to be set to all servers/server group (it should include all the servers which are a part of cluster on Proxmox setup) 

3. Hostname and pvesh get nodes command output return same names.

4. IP pool on Virtualizor panel also needs to be shared (assuming routing part is already handled from provider’s end)
You can choose the servers/group on Edit IP pool page as well.

Virtualizor panel will automatically update server ID for the migrated VPS (when it is live migrated using Proxmox panel) in the VPS table on Virtualizor once all these requirements are satisfied.
