Can you use VM templates? https://pve.proxmox.com/pve-docs/pve-admin-guide.html#qm_templates

You can create 2 bridges in PVE and 2 NICs for the pfSense VM. 1 bridge goes to the ethernet port that goes outwards/to your modem. There you attach the pfSense WAN. 1 bridge goes to the ethernet port that goes to your switch. You attach this to the pfSense LAN and you give this bridge an IP...

Have you tried qm importdisk 100 VM100.qcow2 local-lvm --format qcow2 already?

/dev/sdb should appear in lsblk, so I guess there is none. Is it somewhere in your /etc/pve/storage.cfg? Searching for sdb in the PVE configuration files might also be interesting grep -r /etc/pve -e sdb -C10 You cannot recover a backup of your Ubuntu VM when the backup is inside that VM and...

That's because local-lvm:server_name.qcow2 is not valid syntax. It should (similar to unused0 in the VM config) be local-lvm:vm-100-disk-1 You can manually remove the line from the VM configuration file /etc/pve/qemu-server/100.conf. Note that this will not change the underlying logical...

Hi, have you already been able to solve this? Do you have separate networks for Corosync/Cluster, Ceph, Administration etc? Because it sounds like the migrations saturate your network connection, then the Corosync packages do not arrive in time and then all sort of bad stuff can happen (like...

For the moment I'd use the command line so that 2 (or more) qm migrate commands get executed one after the other. Could you please try to replicate this with command line and post the exact command? And also your /etc/pve/storage.cfg Because so far I have not been able to reproduce the problem.

Hi, what is on /dev/sdb?

Hi, Datacenter->Storage->Add and then LVM and Directory. You can choose existing volume groups for LVM and arbitrary paths as base for directory storages. You might have to mount your disks manually first (for example with /etc/fstab).

Hi, what is the output of ip -c a Generally, I'd suggest using something like tcpdump -envi vmbr1 "icmp" (also on other interfaces) to see where your packages do not pass as planned.

Adding existing drives to a VM is not exposed in the GUI (yet). The easiest way is using qm importdisk. Some usage examples are in the server migration article. There is also a man page for (all of) qm. Using a live ISO could also be an option :)

You should not use a .qcow2 file on local-lvm. It is not supported by Proxmox VE. The Wiki has an overview of all storages and their supported formats. Please use the commands that you find in the migration guide in the Proxmox VE Wiki instead, especially qm importdisk. This will take care of...

Hi, as you mentioned, a lot of this should be solved with SPICE & Qemu Guest Agent.

Can you place an LVM storage on top of your iscsi storage BAIE?

Which commands do you mean exactly? Could you please post cat /etc/pve/storage.cfg The LUNs should probably not appear in the Disks of your Node. But if you add it in Storage->Add then it should still be possible to create disks for your virtual machines on them. Note that for this the...

Im PVE GUI? Wenn du den Adapter wieder einsteckst, ist er dann in ip -c a als DOWN markiert? Dann könnte (mit einem passenden Eintrag in /etc/network/interfaces) ifup <interface> reichen.

Have you added anything in Datacenter->Storage->Add?

Yes, you can use for example scp (winscp) and the home directory.

You can use pvesm status as first step. It writes an error if some (network) storage is unavailable.
