      Hi,
sajolida:
      
        You're right, we're missing proper instructions to do a manual upgrade
of a virt-manager installation with a Persistence. I should fix this.
Now tracked with 
https://redmine.tails.boum.org/code/issues/17187.
      
      
      
        I'm not a user a virt-manager myself and I know that some of us do use
it with a Persistence. It would save me quite a lot of time if they gave
me a synopsis of how they do their manual upgrades :)
      
      
      
        segfault, intrigeri: How do you do that? Do you start the VM on an ISO
image plugged as a DVD and use it to do the upgrade? Something else?
      
      
Essentially yes, but some extra steps are needed to ensure one actually
starts from that virtual DVD:
1. In "Boot Options", ensure the DVD is listed first (or select
   "Enable boot menu" and then you can pick the boot device when
   starting the VM).
2. To tell live-boot to use the SquashFS from the DVD, add this boot
   option:
     live-media=/dev/sr0
   This works for a "SCSI CDROM" device. If the virtual DVD reader is
   plugged into the SATA bus instead, the /dev/sr0 path might need to
   be adjusted.
And then yes, I use Tails Installer to clone the running system and
upgrade the Tails system that's on the virtual USB drive.
Cheers,
