Qubes lag / frozen during template installation / throttle disk I/O of dom0 during Qubes template installation #7268

Open adrelanos opened 2 years ago

adrelanos commented 2 years ago

The problem you're addressing (if any)

During template installation, Qubes become unusable due to high disk I/O

The solution you'd like

Throttle disk I/O of dom0 during Qubes template installation.

The value to a user, and who that user might be

Not seemingly have the impression of a frozen or laggy system, ability to keep multi-tasking during template installation.

Comments

This is most likely not a hardware issue. It's related to how much resources are assigned to dom0 disk I/O versus VMs.

Sounds quite similar to #6660, especially https://github.com/QubesOS/qubes-issues/issues/6660#issuecomment-891945426. Possibly a duplicate?

adrelanos commented 2 years ago

Similar, yes, Duplicate, probably not. Although, if a Qubes developer would decide to work on this it might all be covered at the same time.

6660 has a wider scope, is about VMs. This is about dom0.

Thank you for pointing out the potential duplicate! (Since I was about to research/write such a feature request now - hostile/broken VMs using too much system resources - #6660.)
