Running Ubuntu 14.04 “Trusty Tahir” on XenServer CloudStack

The recently released Ubuntu 14.04 “Trusty Tahir” LTS release comes with Xen HVM (Hardware-assisted virtualization) support. Previous LTS releases supported the older Xen PV (para-virtualization) mode only.

Phoronix has recently published a comparison between Ubuntu 14.04 Xen PV with Xen HVM virtualisation which seems to suggest that Ubuntu 14.04 with Xen HVM performs better than Xen PV on EC2 cloud. You can read the full article at Ubuntu 14.04 On Amazon EC2: Xen PV vs. HVM

CloudStack+XenServer users can also run Ubuntu 14.04 LTS in HVM mode by creating new instance from the installer ISO by choosing the OS type as “Other (32-bit)” or “Other (64-bit)”. My tests were done on CloudStack 4.3.0 with XenServer 6.2.0 hosts with all service packs applied.
