OpenSC smartcards + LVM

[alexandre...@mailbox.org]

Dear all,

This is my first post, so I would like to thank the community  for the hard work around Qubes.

Here are some questions before I consider replacing my system with Cubes.

1) OpenSC smartcards

I would like to use OpenSC smartcard with pinpad reader to secure my SSH key. The pinpad reader is a USB device. Is Qubes suitable for that?

Shall I create a minimal debian template, install OpenSC and libccid, allow USB device. Then shall I run a disposable VM each time I want to access a remote server using SSH?

2) Disc access + LVM

What is the technology used for disc access? The question is that I am considering running a PostgreSQL database and it might be running slowly on a disc image. I read in documentation that dom0 had its own LVM logical volume (LV). I also read that VMs were stored in a disc image.

Can VMs have their own logical volume ?

Kind regards,
