Proxmox device hot-plugging in guests
This should be pretty straightforward, adding: hotplug: 1 to the /etc/pve/qemu-server/VMID.conf file might work and that is for all types of devices ie network, disk, cpu etc. In case the hot-plugging still doesn’t work when device is being added from…
HA Features in Proxmox PVE cluster and final words
At the end, some testing of the High Availability fatures in PVE 4.2 on node and VM/LXC level. Instance Migration Migrating (moving) LXC and VM instances from one node to the other when the instance is stopped works without any…
Cluster Networking for Multi-tenant isolation in Proxmox with OpenVSwitch
This is probably the most complex part of the setup. It involves network configuration of the cluster in a way that the instances running on different nodes can still talk to each other. This is needed in order to provide…
Adding ZFS over iSCSI shared storage to Proxmox
PVE-4.2 has built in support for ZFS over iSCSI for several targets among which is Solaris COMSTAR. I built a ZFS VM appliance based on OmniOS (Solaris) and napp-it, see ZFS storage with OmniOS and iSCSI, and managed to create…
Adding RBD (CEPH) remote cluster storage to Proxmox
There is a 3 node CEPH cluster running on the office virtualization server that is external to PVE. The latest PVE though has built in support for CEPH using pveceph package so in case we have PVE cluster of 3…
Adding iSCSI shared volume to Proxmox to support Live Migration
We will use Multipath for link HA and improved performance. Install the needed packages first: root@proxmox01:~# apt-get install open-iscsi multipath-tools Then we discover the target and login: root@proxmox01:~# systemctl start open-iscsi.service root@proxmox01:~# iscsiadm -m discovery -t st -p 192.168.0.180 192.168.0.180:3260,1…
PostgreSQL Confluence DB replication with Bucardo
In cases where we can’t use the built-in PostgreSQL replication facility, like for example Confluence DB which has replication protection, Bucardo is very efficient option. It is an asynchronous PostgreSQL replication system, allowing for both multi-master and multi-slave operations. Bucardo…
Adding DRBD shared volumes to Proxmox to support Live Migration
The plan is to create 2 resources in Primary/Primary mode. The first one r0 will be used to store disk images for VM’s running on proxmox01 and r1 for the VM’s running on proxmox02. This way we can easily recover…
Adding GlusterFS shared storage to Proxmox to support Live Migration
To be able to move VM’s from one cluster member to another their root, and in fact any other attached disk, needs to be created on a shared storage. PVE has built in support for the native GlusterFS client among…
Proxmox clustering and nested virtualization
The motivation for creating this setup is the possibility of having Encompass private virtualization cloud deployed in any third party infrastructure provider DC, like for example SoftLayer that we already use to host our product on Bare-Metal serves. The solution…
