[PVE-User] Proxmox VE 6.4 released

[PVE-User] Proxmox VE 6.4 released

[Martin Maurer]

Hi all,

We are proud to announce the general availability of Proxmox Virtual Environment 6.4, our open-source virtualization platform. This version brings unified single-file restore for virtual machine (VM) and container (CT) backup archives stored on a Proxmox Backup Server as well as live restore of VM backup archives located on a Proxmox Backup Server.

Version 6.4 also comes with Ceph Octopus 15.2.11 and Ceph Nautilus 14.2.20, many enhancements to KVM/QEMU, and notable bug fixes. Many new Ceph-specific management features have been added to the GUI. We have improved the integration of the placement group (PG) auto-scaler, and you can configure Target Size or Target Ratio settings in the GUI.

The new version is based on Debian Buster 10.9, but using a newer, long-term supported Linux kernel 5.4. Optionally, the 5.11 kernel can be installed, providing support for the latest hardware. The latest versions of QEMU 5.2, LXC 4.0, and OpenZFS 2.0.4 have been included.

There are some notable bug fixes and smaller improvements, see the full release notes.

Upgraded from 6.3 with no problems on my single node, non-ceph home 
server (CT only). Kernel update, so needed a reboot.

Thats amazing, tested and works as advertised. Could see this being very 
useful.

How on earth do you do that? are you retrieving disk sectors on the fly 
as needed from the backup server?


Great release! Will probably upgrade our PX/Ceph cluster at work over 
the weekend.

Yes, we plan on adding support for LVM, ZFS and mdraid in the future. 
For now only filesystems directly on partitions are supported.

NTFS is supported already, file restore from Windows guests should be 
possible.

Ah that's an unrelated issue with virtio drives, should be fixed by 
'proxmox-backup-file-restore 1.1.5-2' currently in pvetest. We found 
that issue a bit too late for the release, unfortunately.

See:

Did a rolling upgrade on a 5 node ceph cluster, 6.3 => latest, rebooted 
all nodes. No issues at all.


I did notice that on the dist-upgrade, the grub update generated a 
number of errors:

The following packages will be REMOVED:
   pve-kernel-5.4.78-2-pve
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.

[PVE-User] Live restore & Vlan Config

[Fabrizio Cuseo]

Hello.
Do you know if there is the possibility to change vlan id (or some other VM configuration data) before starting a live restore ? It will be useful to make some test from backup without waiting all the time needed for the traditional restore.

Regards, Fabrizio

Hi,

at the moment this is not possible, you have to use a regular restore and change the config before starting. This is something we're considering adding in the future though.
