Cool! Since this uses LXC 4.0, is now cgroup v2 (unified hierarchy) used? Especialy for memory controller to limit swap properly?

Some initial cgroupv2 support from our container toolkit (pct) is in fact included, but you need to boot the host into cgroupv2 to be able to use it, both versions cannot really co exist on a system. The support will be improved over the next releases.

Nice to hear that. What are the downsides of booting with cgroupv2 (and therefore disabling cgroupv1)? Will it break something important?

For now I wouldn't recommend it for production systems. It really shouldn't break anything but some limits aren't yet enforced at all and some CT distros may complain about v2 if they're on older releases, I'd guess.
 
Hi! Congratulations on the release!
How can I install this with encryption for data at rest for the OS disk?
This is important because my private cloud is not as securely physically stored as it should be. Any better and more secure solutions is outside of my budget. Therefore I seek to encrypt data at rest for all data storage containers, including the OS disk.

  • Enable support for Live-Migration with replicated disks

I updated from 6.1 to 6.2 but when I try to migrate a VM I get the following error Message:

2020-05-12 15:51:12 starting migration of VM 103 to node 'XXX' (XX.XX.XX.XX

Or is live Migration not possible in the GUI?

It is, albeit the "Target Storage" selector isn't yet smart enough to prefer already replicated storages for a VM, if any, so you need to select the correct one yourself for now.
Also, ensure you reloaded the webinterface cleanly (as else you may still use a backend worker with the old code not yet phased out).
 
I only got 1 Storage (for VM and CT Images) on each host.

Seems like the issue was caused by HA. As soon as I removed the VM from the HA group it migrated totally fine.

Is it possible, that it the migration, if issued by HA, is missing the "with-local-disks" option for migration? (Linke the logs are saying ^^)

Hmm, we pass force to ignore some local checks but yes, "with-local-disks" isn't yet passed.Can you please open a enhancement request over at our bug an feature tracker: https://bugzilla.proxmox.com/

Just set up ACME using DNS and it's easy mode!

Looking forward to not having to copy my wildcard certs to each proxmox node when the old ones expired.

that is a symptom not the cause of the actual error. Please open a new thread and check the syslog / journal for errors, post your network config.

Hi t.lamprecht

I have managed to get this message gone by using the below commandm

sudo dmesg -n 1

after this the messages stopped and I could investigate what went wrong,

It seems the package below was not upgraded or removed during upgrade and this is required for Bonding

ifenslave

Please can you confirm if there is a new way of doing bonding interfaces on Openvswitch?
