Here is a simple way to setup key (password-less) login on Unix-like systems.
Once you’ve configured SSH locally, add your public key to remote hosts using the following command:
After answering the password prompt, your public key will be appended to the remote ~/.ssh/authorized_keys2.
Remember to make sure the remote folder ~/.ssh is set to mode 0700 and ~/.ssh/authorized_keys2 to 0600, or auto login will be disabled.
Adding existing logical volumes to the list of virtual disks is non-obvious.
First add the VG to Proxmox using the “Storage|Add” UI. Once done, adding existing LV to Proxmox must be done via LVM command line tools.
A logical volume needs to have the correct naming, and (surprise!) an LVM tag set. For the correct tag (and LV name) format, use the UI to create a sample volume (VM|Hardware|Add|Hard Disk).
Note: LV names must fit a certain pattern. However, names like this seem to work: vm-110-timemachine.
The example below shows a pre-existing LV (vg1/vm-110-disk-2) without the “pve-vm-110” tag Proxmox requires.
Subsequent steps add the tag, after which the volume appears in Proxmox.
# lvs -o vg_name,lv_name,lv_tags
VG LV LV Tags
vg0 vm-110-disk-1 pve-vm-110
vg0 vm-110-disk-2 pve-vm-110
vg1 vm-110-disk-1 pve-vm-110
To see LV tags:
# lvs @pve-vm-110
LV VG Attr LSize Pool Origin Data% Move Log Copy% Convert
vm-110-disk-1 vg0 -wi-ao--- 500.00g
vm-110-disk-2 vg0 -wi-ao--- 750.00g
vm-110-disk-1 vg1 -wi-ao--- 750.00g
To add missing tags:
# lvchange --addtag pve-vm-110 /dev/vg1/vm-110-disk-2
Refresh the Proxmox Storage UI to see the new LV.
It seems this is filled with multiple (roughly) 1GB swap files, allocated as required.
Problem is they don’t go away (until reboot?).
One article suggested this:
sudo dynamic_pager -L 1073741824
Seemed to work: before running vm used 8GB, afterwards 4GB
Generally I like to run servers headless, as in with no display or console. In Parallels this is a little tricky, but doable from Terminal. However, Parallels Desktop must not be running. If you do launch Parallels while a Terminal-spawned VM is running, a console will automatically be created.
To see a list of available VM:
prlctl list -a
To launch a VM:
prlctl start vm_name
