Description of problem:
When user creates some VM in RHV webadmin portal, 'Single PCI' checkbox is checked or disabled (unchecked) according to chosen operating system. For example if RHEL 6.x is chosen, check-box is checked - if Windows OS is chosen, check-box is disabled.
Lets say we have VM of some operating system by choice of which the check-box is disabled (e.g. Windows OS VM).
If 'Operating system' is edited after VM creation to e.g. RHEL 6.x, Single PCI checkbox is not automatically checked as is before VM creation.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.create new VM of some operating system when 'Single PCI' checkbox is set to disabled state (e.g. Windows*, Other OS..) in rhv admin portal
1a. notice 'Single PCI' checkbox is automatically checked if some RHEL6/7 OS is chosen
2. Edit this VM and set operating system to type when 'Single PCI' checkbox should be checked (e.g. RHEL6/7)
'Single PCI' checkbox is not checked
'Single PCI' checkbox should be checked like during VM creation step.
This will not be addressed in a reasonable timeframe. Please re-open if it's still important.
I reproduced this again in latest rhv4.2.
The thing here is that multiple PCI is not supported for Linux guests - that means (from my experience) they usually become unstable.
and Doc text of the same bug. Therefor I think it is not good to unnecessarily increase probabilty for user to have linux VM with multiple PCI devices.
I do not why single PCI checkbox exists at all after such discussion .. maybe it is time to get rid of it.
Either way, if you want to get rid of checkbox or not, IMHO to correct checkbox behaviour according to drop down list is pretty low hanging fruit.
Tou reproduced the crash with RHEL 7.6?

You probably mean crash from https://bugzilla.redhat.com/show_bug.cgi?id=1428340 ? No I cannot reproduce this. But multiple monitors (Monitors>1) does not work with rhel7.6 guest when I set multiple PCI devices ('Singe PCI' is not set). Only one display is available.
This bug didn't get any attention for a while, we didn't have the capacity to make any progress. If you deeply care about it or want to work on it please assign/target accordingly
'Single PCI' checkbox is not present in rhv-4.4.0-0.25.master.el8ev. So closing this.
