Not sure how comparable they are since I never used Monodraw due to not running MACs, but there is https://asciiflow.com/ and https://monosketch.io/ which I usually use. The latter is using some advanced UTF8 characters and when trying to get it incorporated for my personal blog, I had to use their specific monospaced font from their repo, as otherwise lines wouldn't line up correctly.

don't enable it though, if you rely on the guest replication feature of PVE. See https://bugzilla.proxmox.com/show_bug.cgi?id=2350 for why

Hmm, staying with iSCSI. You should create one large LUN that is available on each node. Then it is important to mark the LVM as "shared". This way, PVE knows that all nodes access the same LVM, so copying the disk images is not necessary on a live migration.
With such a setup, PVE will create LVs on the same VG for each disk image. So no handling of multiple VGs or LUNs is necessary.
The multipathing PVE wiki page lines out the whole process: https://pve.proxmox.com/wiki/Multipath

That should have been possible for a while. Get the block storage to the node (FC or configure iSCSI), configure multipathing in most situations, and then configure LVM (thick) on top and mark it as shared. One nice thing this release brings is the option to finally also have snapshots for such a shared storage.

In case the author reads this: instead of `losetup` you could have imported the image with `qm disk import VMID path/to/source TARGET_STORAGE`
It would then show up as unused disk in the VM config to be further configured :-)

hmm, if you refer to the `qm` command, that is not from Qemu itself but a Proxomx CLI tool :)

Proxmox VE is using LXC for the containers directly. But no LXD.

This helped me when I was using them some years back during my university time. Managed to place some papers on a heater and the ink disappeared. Putting it in the freezer for a bit made it all come back.

RAM and other state can be part of a snapshot for VMs, in which case the VM will continue right where it was.
The state of a container is not part of the snapshot (just checked), as it is really hard to capture the state of the container (CPU, network, all kinds of file and socket handles) and restore it because all an LXC container is, is local processes in their separate cgroups. This is also the reason why a live migration is not really possible right now, as all that would need to be cut out from the current host machine and restore in the target machine.
This is much easier for VMs as Qemu offers a nice abstraction layer.

That highly depends on the underlying storage. If it is something that supports snapshots (ZFS, Ceph, LVM thin) then it should work fine, also backups will be possible without any downtime as they will be read from a temporary snapshot.

If you install Proxmox VE the next time and are not happy with the default layout, check out the parameters for LVM [0]. I personally prefer to install on ZFS as all ZFS datasets share the same free space unlike with LVM.
If you want full control of the disk layout and maybe want to do some more custom stuff, consider installing a base Debian and then install Proxmox VE on top of it [1].
The PVE installer makes it easy to get a system up and running quickly but is opinionated what the disk layout should be. That of course might not be working for everyone.

works in combination with the Proxmox Backup Server (PBS).
