Virtualbox 6.1.30 hangs/freeze when using any Virtualbox controls on VM

Guest OS: Ubuntu 20.04

Virtualbox 6.1.30 hangs/freeze for ~2 minutes when using any VirtualBox controls on VM window (Click X to close the VM and save state, Mount CD, etc) and getting this message in the logs:

VMMDev: vmmDevHeartbeatFlatlinedTimer: Guest seems to be unresponsive. Last heartbeat received 155 seconds ago

One thing you have that's off is too new Guest Additions:

00:00:05.466436 VirtualBox VM 6.1.30 r148432 win.amd64 (Nov 22 2021 15:15:30) release log
00:02:26.847499 VMMDev: Guest Additions information report: Version 6.1.32 r149290 '6.1.32'
00:02:15.120162 3DEnabled <integer> = 0x0000000000000001 (1)

The host Virtualbox wasn't programmed for Guest Additions that didn't exist yet, especially so when there is an intense API channel in use, 3D acceleration.

I'd try two things:

1. Make a new VM with a fresh install of the old VM's OS from the installer ISO. See if Virtualbox seizes up with the new VM.

2. Back up the old VM by copying its folder and any disk files outside the folder while the VM has been fully shut down. Then uninstall Guest Additions inside the old VM. Does the seize-up stop?

I still have the same issue... vm freeze for 183 seconds after I try to suspend it

See in the logs:

Code: Select all

00:36:22.521424 Changing the VM state from 'RUNNING' to 'SUSPENDING'
00:39:26.516347 PDMR3Suspend: Driver 'VD'/0 on LUN#0 of device 'ahci'/0 took 183 994 824 756 ns to suspend
00:39:26.580630 PDMR3Suspend: 184 059 132 836 ns run time
00:39:26.580654 Changing the VM state from 'SUSPENDING' to 'SUSPENDED'

I still have the same issue

Not exactly. This:

VMMDev: vmmDevHeartbeatFlatlinedTimer: Guest seems to be unresponsive.

isn't the same as:

00:39:26.516347 PDMR3Suspend: Driver 'VD'/0 on LUN#0 of device 'ahci'/0 took 183 994 824 756 ns to suspend

The first is where the VM OS stops working. The second is where either the host disk or the VM's "disk" responded slowly or not at all for a time.

Both might be from an underlying problem.

You upgraded the host Virtualbox to match the VM's Guest Additions, good.

How did this work out:

Make a new VM with a fresh install of the old VM's OS from the installer ISO. See if Virtualbox seizes up with the new VM.
