Hi, thank You very much for the script. Is there any way to specify from the command line how many displays to start? I have 3 monitors at office, but only 1 at home. Need to use checkboxes at the virt-viewer menu. I'm using virt-viewer to specify how many displays is connected to the my VM, but...
Forwarded ports 8006 and 3128 from the router to the proxmox node, I see a spice proxy from Internet via nc, but can't connect to a vm. Seems that something is missing. Got "connection refused".

Resolved.
Problem was with the user name in the mount command:
$ sudo mount.ceph admin@8fc87072-5946-466f-a10a-6fa9bd6fa925.cephfs=/ /mnt
$ df -h /mnt

When I'm trying to mount cephfs from the proxmox cluster 6.4 with ceph 15.2.15 to the vm client Ubuntu 22.04 I'm getting an error:
$ sudo cat /etc/ceph/ceph.conf
[global]
auth_client_required = cephx
auth_cluster_required = cephx

I'm using ZFS over iSCSI storage. ISCSI provider - LIO. ISCSI server - Proxmox backup server with a kernel 5.11. PVE version - 6.4.6 with a kernel 5.11. When create or remove VM disk, create or remove a snaphot there from the PVE GUI, I'm getting error messages from another LUNs: qemu-img: iSCSI...
On Ubuntu 21.04 it's also work. Thank you.

Even number of Ceph monitors, half of it in an every of 2 locations, not looking as a very good idea, because if link on a Ceph network will be broken, the entire cluster will stop working. Better make 2+1 ceph monitors. In this case the location 1 will survive, when Ceph network between...
I have servers with different CPU models in a cluster. So, want to create the config file /etc/pve/virtual-guest/cpu-models.conf with common flags for all my CPU. Is there any tool in Proxmox to automate this task? Manually compare flags and create config is a very long and error prone task...
After setting speed limit to 8GB/sec it's much better:
2021-05-01 14:08:47 use dedicated network address for sending migration traffic (192.168.122.5)
2021-05-01 14:08:47 starting migration of VM 117 to node 'asr5' (192.168.122.5)
2021-05-01 14:08:48 starting VM 117 on remote node 'asr5'...
I see that live migration goes much slower after updating all cluster to the 6.4. Here is a dedicated migration network 10Gb.
root@asr5:~# cat /etc/pve/datacenter.cfg
keyboard: en-us
migration: network=192.168.122.1/24,type=insecure
Now it is:
2021-04-30 00:33:14 use dedicated network address...
When I'm trying to rename a vm from a web gui, it doesn't accept at least "-" and ".", even if an original vm name contains minus and dot.
root@asr5:~# pveversion --verbose

I used firefox on Ubuntu today to add the node. There was no problems. May be your problem is related to a DNS name resolution. Try to add the cluster nodes to /etc/hosts at the existing nodes and the new node.
Did you tried to close a web browser and login to there again after adding a node? Today added a node to a cluster wia web GUI, all was fine. Forgot to turn on a nested virtualization at the new node, as it was set at other nodes and migrations to the new node have failed, but it's another question.
Thank You for the advice. Now configured bond 2x10Gb for both public and private Ceph networks. Will see.
iface bond0 inet manual
bond-slaves ens4f1 ens4f2
bond-miimon 100
bond-mode balance-tlb
mtu 9000
Also created a bridge there to provide Ceph inside VMs, for...
Replying to myself. Problem was not related to the last proxmox update. I have added a new node to cluster, but forgot to turn on a nested virtualizaton there according to the guide. Without this option migrations of windows 2012 server and ubuntu 21.04 guests has failed to there. After turning...
