Nibbles for us neophytes:
I utilize pre-existent, unencrypted ext4 logical drives in an extended partition of the system resident HD that have evolved from a lengthy legacy of linux distros. I want specific slices to auto-mount in selected VMs which I’ve set to autostart on Qubes boot.
Set selected VM to autostart: In VM’s Settings, under “Basic” tab: check Start qube automatically on boot box.
(Don’t know if a qube restart is necessary at this point.)
Determine the dom0 device name from Qubes Devices widget, or in target VM terminal, enter
sudo sfdisk -l
(e.g. “sda [+ number]”)
Open a dom0 terminal and enter:
qvm-block attach --persistent <VM> dom0:sda[*]
In target VM terminal, confirm the designator for that slice:
If not already done, create the mounting directory:
Edit as root the target VM’s
/rw/config/rc.localfile and enter:
mount /dev/xvd[*] /home/user/<dir>
Restart the qube.
I’ll amend this post for errors & omissions, should the need arise.
