Hi All!

I have a Linux Fedora 32 based server, where I installed the VirtualBox 6.2.
I made more vms with Fedora 32 in the VirtualBox, and everything works fine until yesterday.
I don't really knows what happened, what changed, but the virtual machines not really wants to boot. Sometimes they boot, sometimes don't.

Here are some ends of vms log file at the times when the virtual machines didn't boot:

It's very weird.. what's going on?

I attached full log one of vms. I hope somebody could help me.
Thanks in advance!

The guest log posted is incomplete, it either came from a complete failure in Virtualbox on the host, or the guest Virtualbox window was still open.

Start the guest from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the guest from within the guest OS if possible. If not possible, close the Virtualbox window for the guest with the Power Off option set.

Right-click the guest in the main Virtualbox window's guest list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.

It would be best to provide a log from a guest that fails to boot and another log from the same guest when it boots and shuts down properly.

Hi scottgus1,

thanks for your reply.
I attached the logs from a good and a bad case.

tesztjoinhoz-2020-06-10-10-09-31.log - it fails to boot, close the Virtualbox window for the guest with the Power Off option set.
tesztjoinhoz-2020-06-10-10-13-11.log - it boots and shuts down properly.

Hi scottgus1,

Were you able to view the logs? Did you find any problems?

I would start by updating both VirtualBox and the Guest Additions. The latter especially are still on the 6.0.0 version, by definition the buggiest possible in the v6 branch.

I'd also allocate two cores to the VM, and increase graphics RAM to 128MB.

I too see the failure to continue running after

00:00:10.139538 PIIX3 ATA: Ctl#1: RESET, DevSel=0 AIOIf=0 CmdIf0=0xa0 (-1 usec ago) CmdIf1=0x00 (-1 usec ago)
00:00:10.139589 PIIX3 ATA: Ctl#1: finished processing RESET

But what I also see is that the failure-after-reset guest continues processing Virtualbox commands and log entries and closes properly after the user requests to close the Virtualbox window:

00:00:10.139538 PIIX3 ATA: Ctl#1: RESET, DevSel=0 AIOIf=0 CmdIf0=0xa0 (-1 usec ago) CmdIf1=0x00 (-1 usec ago)

The other good-boot log shows the guest OS continuing after the RESET line.

This shows me that the issue resides in the guests or on the host PC somehow, not in Virtualbox itself. I may be wrong, but from the info posted I cannot see what might be wrong from a Virtualbox standpoint.

One suggestion in the future, be sure to take the log after the guest Virtualbox window is fully closed. Your first log also stops at "PIIX3 ATA: Ctl#1: finished processing RESET", but the other logs posted later indicate Virtualbox does continue processing. The log in the first post was taken while the guest OS had seized but before the Virtualbox window was closed. Your log snippets in the

Code: Select all

 tags also suffer from the same problem.

One other possibility. You state your host PC OS as Fedora 32. If I recall correctly, Fedora 32 did not exist when Virtualbox 6.1.6 came out. Maybe a Virtualbox upgrade is in order. Also, check on Mpack's thoughts on the Guest Additions. 6.0.0 GAs are really old.

After the updating both VirtualBox and the Guest Additions, it seems that every guests work fine.

The version of Guest Additions was 6.1.6, not 6.0.0

However, I see that the version number is 6.0.0 was in the log. After the update the version hasn't changed in the log:
00:00:15.651073 VMMDev: Guest Additions information report: Version 6.0.0 r127566 '6.0.0'

Probably, is it a log bug?

Thank you guys!

Nope.

Short answer: the log doesn't lie. If it reports an unexpected GAs version, then you didn't install the GAs.

Also the dialog box you picture is telling you about the host extension pack, which has nothing to do with the GAs.

mpack wrote: you didn't install the GAs.

I'm sorry, I mixed the GAs with the Extension Pack.

Good! Glad you're up and running.
