Virtual Machines

We are running two KVM hosts to run virtual machines on in the space.

Hardware

vmhost01

WebUI: https://10.10.20.62:8006/

• 2x Intel Xeon 2,0 Ghz
• 18 GB RAM
• 2x 150GB (SW RAID1) Boot drives
• 8x 500GB data drives (in a ZFS RAIDZ2, leaving about 2.8 TB of space)

vmhost02

WebUI: https://10.10.20.65:8006/

• 2x Intel Xeon 5130 (2,0Ghz)
• 16GB RAM
• 2x 250GB (HW RAID1) boot drives
• 14x 143GB data drives in external SCSI shelf, not all of them working (in a ZFS RAIDZ2, leaving about 1.2 TB of space)

Software

We are running Proxmox on the machine. Installation was done manually on a Debian Jessie install roughly following Proxmox's guide, as their standard installer does not support software RAID for boot devices, and didn't recognise our additional SATA controller.

There are two working datastores, one called "internal" which points to the ZFS raid array, and another called "local" which is on the boot drives. Use the one on the bootdrives for ISO images, and the ZFS array for everything else. Ideally, ISO images will be pulled from the fileserver, but that just hasn't been successfully setup yet.

Fixes

• Had to apply https://forum.proxmox.com/threads/lxc-nfs.23763/ to get the Backup container to mount an NFS share
