Re: [qubes-users] Re: qubes 3.2: qubes-vm-manager not consistent

[ludwig jaffe]

Hi thanks,

I edited
/var/lib/qubes/qubes.xml
and removed the lines with the names of the VMs I deleted by hand before,
and needed to kill qubes-manager and to restart it, so the file gets read
and parsed.

Now my system behaves like before.

But there should be a warning if one configures the private.img size bigger
than the disk array holding the /var/lib/qubes stuff.
So qubes-manager should summarize the space used by the private.img and
warn the user not to take more space then the disk array can provide.

Oh thank you I am a bit stupid,
I did not try the show hide button! Shame on me :-)

But still I have that zombie-VMs that I removed the hard way.
So I need to de-register them.

Ok I found the file, backed it up and want to edit it.
Do you know an xml ediitor with folding to edit this with more comfort,
as there is no  in the xml, just spaghetti.
A vim for xml with folding or something like that with curses text gui woud
be best.

If you are sure you want to manually edit the qubes config, it's in
/var/lib/qubes/qubes.xml. Make sure to make a backup of it first.

Re: [qubes-users] Re: qubes 3.2: qubes-vm-manager not consistent

[ludwig jaffe]

Yes, I want to repair my qubes-vm-manager.
When I say at dom0:
qvm-ls, then I see my VMs also the vms that I deleted in order to get space
by saying rm -rf /var/lib/qubes/appvm/asterisk-now (some stupid appliance,
I tested,
and wanted to dispose, in order to free up space, which was not successfull
because
of file system errors.
So I cleaned the file system and made a back-up and I want to modify config
files
by hand so the tools do what they should do.
So I need to de-register the vms I deleted by hand,
and I need to tell qubes-vm-manager which vms are there. I wonder if it
uses the tools qvm- in order to do its work.

So I want to fix my old qubes 3.2 and then see if qubes 4 is really stable.
So any help is welcome on fixing my qubes 3.2 to give it the last polish to
remove the last traces of the disaster

Thanks,

Ludwig

I'm sticking with 3.2 on my primary system until 4.0 is released, but rc4
is looking like it will be pretty close to ready.

Are you talking about your two questions above?
In Qubes Manager, go to the View menu and click Show/Hide Inactive VMs.
If you are trying to enter a smaller number to shrink it, I don't think
you can. Back up the personal VM's data, delete the VM, create a new one,
and restore the data.

Hi, as there is RC-4 of something, it is clever to stick with qubes3.2 until 
there will be 4.1.
Also I would like to know how the qubes manager works, in order to fix it my 
self (maybe, I need to edit some XML), if nobody wants to help.

Now I know you're talking about Qubes 3.2. here, but this issue might possibly 
be related to Qubes 4. The Qubes VM Manager was originally planned to be 
out-phased in Qubes 4 and was supposed to become a relic of the past. But due 
to many people having an easier time having a visual GUI that the VM Manager 
provides, the Qubes developers brought it back recently in Qubes 4. However it 
still needs some updates and fixes before it can run a bit more smooth.

So here's thhe thing. Due to limited time and busy schedules to make everything 
for Qubes, I suspect that some of the updates designed for Qubes 4 has also 
arrived and mixed in with Qubes 3.2. to some extent. For example updates in 
qvm-usb, updates to the Qubes-tools, and so forth.

Now that doesn't mean all packages that resides on both Qubes 3.2. and Qubes 4 
are equally updated. All I'm suspecting here, is that "some" might slip through 
to Qubes 3.2.

Basically, in Qubes 4 the Qubes mechanics has become so different, that the 
VM-Manager will take major re-work to make it work properly again. However it's 
already been brought back to a state where it's useful, albeit a bit slow. But 
the cool thing with the Qubes 4 VM-Manager is that the window now can be 
re-sized, although it doesn't yet remember the previous window size, but 
hopefully that's fixed sometime soon.

Either way, this could be a possible explanation, but I'm no expert, and this 
is only and merely a suspicion. Qubes 4 required a lot of work, and they're not 
quite done yet either. They're busy with it, and it's probably taken longer 
than anyone ever expected, although it has brought about some really good 
results so it's imho been well worth it.

Thing is though, Qubes 3.2. was probably not meant to be around this long, and 
it might be starting to show. But that's just be postulating, there might be 
another possible explanation.

But for what it's worth, having used Qubes 4 since RC-2, it's actually become 
quite stable now. If RC-4 is not out soon, then maybe upgrade to Qubes 4 RC-3? 
Also updates meant for RC-4 has been posted to Qubes 4 RC-3 current-testing 
too. Although it reamins to be seen whether a re-install is recommended between 
RC-3 and the yet to be released RC-4, the developers will tell us on the 
release day in the release news article, if any of the previous releases 
procedures is to go by.

Also there is a bug in the qubes-vm manager:
The dom0 disk can become full, as one can set a size for private.img that is 
bigger then the size of dom0 disk!
So if one is not careful, a bigger download in one of the app-vms can render
the qubes-os box unusable and one has to recover the data using kali and 
mounting the file system images.
