Today proxmox version 1.6 was released featuring tools from upstream qemu 0.12.5 and OpenVZ support. There was in fact one feature removal of KSM ( kernel samepage merging ) due to lack of support for this feature in openvz. This release is based on linux kernel 2.6.32 and the corresponding DRBD version 8.3.7.

Below shows the official changelog

• New 2.6.32 kernel including OpenVZ support, based on latest Debian Squeeze Kernel
• Removed KSM (OpenVZ does not support KSM)
• DRBD tools: update to drbd 8.3.7
• New KVM user-space tools (0.12.5)
• New OpenVZ user-space tools (vzctl 3.0.24)
• vzdump: use ionice to set io priority. By default, we now set "ionice -c2 -n7" to limit io (instead of using a default bwlimit)
• vzrestore: new --force option to overwrite existing data
• dab bug fix: only print a warning for packages installed directly with 'dpkg' (when there is no information in 'available' list)
• dab: only mount /proc/ if not already mounted (avoid problems with vzctl 3.0.24)
• Bug fixes
