It should. Can you provide more details? Then we might spot why things go wrong. Contents of /etc/network/interfaces and if you did changes via the UI, but haven't applied them yet, the contents of /etc/network/interfaces.new.

Zwei Stück 10G NICs und ein (DAC) Kabel dazwischen kosten zum glück auch nicht die Welt. ZB die Aquantia Chipsätze sind recht günstig. Man muss nur aufpassen, dass die NIC einen Chipsatz hat der vom Kernel supported wird...

I assume that press releases are probably a better source than the associate forum post? https://www.proxmox.com/en/about/company-details/press-releases For the 24/7 and North America announcement...

With the right tools, you can automate such environments quite easily. For example, use Ansible to spin up the VMs and tear them down again after the training. With some additional work around that, you can make sure that each instance gets a different IP address on the network. Rough outline...

Yes, any executable works. As in the Perl based example, the hookscript will get a few parameters that you will need to handle. So it can be another scripting language like python or bash, or you might compile your own little program.

@zikou those are pretty much the needed steps, except that usually you would symlink /etc/machine-id to /var/lib/dbus/machine-id so that they definitely share the same content. And to recreate SSH host keys, one can use a systemd unit like the following: https://learnlinux.link/ssh-reset...

Because on Linux, usually the machine ID is used to identify against the DHCP server. Windows usually takes the MAC address. Lookup how you can prepare a Debian based system (which Proxmox VE is) to be a template. You usually need to empty the machine ID, so that a new one is created on the...

Lowering the threshold, for ballooning and KSM can mitigate issues on the host, as it will start reducing memory more aggressively when the host still has plenty of resources.

I took a look at the code again, and AFAIU (which might be wrong), pvestatd initiates the Balloon changes here: https://git.proxmox.com/?p=pve-manager.git;a=blob;f=PVE/Service/pvestatd.pm;h=34f9da71fd05ee3c9c5cd1e09d25fe9832eb3364;hb=HEAD#l296 The calculation regarding which VMs are told to...

The installer sets up things with sane defaults that will get most people started quickly. A Linux bridge can do a bit more and will happily accept an IP configuration. As do managed physical switches too. If you do not like or need the default config, feel free to adapt it. For example, if...

Once the threshold is reached, the host will ask the VMs to return memory to the host. The VMs need to be able to return that memory! That means, a way to communicate with the host via the Ballooning device, and free memory that can be returned. The return of memory happens in chunks of ~100MiB...
