[PATCH manager 0/4] fix #7801: ui: warn about problematic virtio versions on iso select

[PATCH manager 0/4] fix #7801: ui: warn about problematic virtio versions on iso select

[Nicolas Frey]

fixes #7801 by scanning for virtio filename regex and warning the user
if the version has known issues attributed to it [0].

I tried the following approaches to warn the user:
- via a (quite intrusive) pop-up
- a warning box after the iso selector
- an inline hoverable icon on the selector field

I felt the second approach resulted in the best UX, so I went with
that in this series. If we have any better/more standard way to warn
about things like these which I missed, please LMK!

[PATCH pve-manager 1/4] ui: iso selector: add option to warn about virtio versions with issues

[Nicolas Frey]

based on the known issues as seen on the wiki. If warnVirtio is true,
the filename is matched against "virtio-win-x.x.x.iso" and checks
whether the version number in the filename is in any "from - to" version
range in `virtioIssues`.

based on whether the ostype is windows or not. extends the
`editorFactory` to allow extraOptions to be a callback to allow for lazy
evaluation. this is needed as 'ostype' is not yet instantiated when
eagerly evaluating.

I built these patches on top of the current head 14a22df35.

Some things I noticed:

- The `pmx-hint` class is generally used for such warnings. The current
  approach of an icon works for me, but it does not match how it is done
  in multiple other warnings.

- The message "'Upgrading to version 0.1.266 or newer is recommended."
  might lead a user to try with the current latest version (0.1.285)
  which will then warn them to downgrade. Perhaps mention that 0.1.215
  up to 0.1.262 (including/not including) can have read errors and
  performance issues and let the user make a decision based on that.

- Same with the downgrade message one sees when trying 0.1.285. These
  messages should remain accurate and relevant after we get new releases
  of the VirtIO drivers (which might or not have more issues).

- The Hardware panel does not load. I see the following error in the
  console:

Uncaught TypeError: can't access property "getById", me.store is undefined

when going to the Hardware Panel of a VM. I am not 100% sure this is
caused by the changes here, but the error is gone after downgrading to
the version in staging.

One thing I was not able to test was whether these warnings were also
visible for VMs having a ostype different than windows.

thanks for testing the changes! I'll change the gettext call you mentioned in
patch 1/4 and apply your suggestions from here.

as for the hw panel not loading: I did run into this issue and (at
least thought that) I fixed it by lazily retrieving the ostype in the
`editorFactory`, as after that change I didn't run into the issue
anymore. I'll test it myself tomorrow to see if I can reproduce it.

Thanks for the review!
