VB Freeze while using multi cpu

Reported by: Alexey Kuznetsov Owned by:
Component: other Version: VirtualBox 4.2.16
Keywords: Cc:
Guest type: Linux Host type: Mac OS X

Description

VB Freeze every 30-60 minutes while compiling the cyanogenmod.org repo. Hudge IO operations cause application to freeze and do not respond to any click. Even VB GUI application frezze until you kill VB Guest.

1 CPU does not freeze (but it takes forever to comiplie the source, so i havent tested it mutch)

playing with it all day:

  • vbox can hungs even at boot if numbers of CPU's > 1 (even 2 will stuck the VB)
  • i have anohter notebook with i7 cpu, with 4 cores - no hungs
  • seems like it is only Mac Pro issue with 2 x 2.93 GHz 6-Core Intel Xeon (24 cores)

my laptop cpu: 2,66 GHz Intel Core i7

working fine even for 4 cpu running.

comment:3 by Alexey Kuznetsov, 11 years ago

it is standing on night long with 1 cpu and 2 x 2.93 GHz 6-Core Intel Xeon with no issues.

4.3 keep hunging

comment:5 by Frank Mehnert, 11 years ago

You have 12 physical CPU cores and you assign 24 virtual CPUs to your guest -- how should that work? Do you still experience these hangs if you assign not more than 12 virtual CPUs to your guest?

comment:6 by Alexey Kuznetsov, 11 years ago

I have 12 real cores + hyperthreading for each. Normally linux and all apps detecting 24 cors.

Processor 2 x 2,93 GHz 6-Core Intel Xeon

including VirtualBox. It allows me to assign 24 cores (saying it is a max).

Now it wont even boot, hungs at the begining. 12 hungs as well at boot.

comment:7 by Frank Mehnert, 11 years ago

Hyperthreads don't count, please never use more than 12 guest CPUs. It's still unclear why the VM hangs with 12 guest CPUs. Are you running several VMs in parallel?

comment:8 by Alexey Kuznetsov, 11 years ago

nope. only one machine. even if i use 2 cores it hungs (can't confirm it for 4.3VB yet, takes some time)

comment:9 by Alexey Kuznetsov, 11 years ago

and about your statement about cores. now i'm runining VB with 2 cores attached. cat /proc/cpuinfo also shows 2 cores (i can assume, if you suggest not to use hypertreading cores with vb, then vb shall emulate hypertreading by it self, but it doesnt)

comment:10 by Frank Mehnert, 11 years ago

VirtualBox does not need to emulate hyperthreading. Just don't count the hyperthreads when considering the number of virtual CPUs, that's it. That's a general remark, not necessarily related to your hang problem.

comment:11 by Frank Mehnert, 11 years ago

Oh, I forgot to ask: What kind of guest are you running?

comment:12 by Alexey Kuznetsov, 11 years ago

Host: Mac 64, Guest: Ubuntu 64

comment:13 by Alexey Kuznetsov, 11 years ago

On Maveric, it does not hungs, but also does not load more then 2 cpu (200% on the activity maganer) even if I have more then 2+ CPU assigned to the VB

comment:14 by Alexey Kuznetsov, 11 years ago

On the same hardware a have native linux installation and VB on it. It has no issues even with 24 CPUS!

So. Here is a two reasons why it is a OSX HOST issue ( 1) maverics act different 2) linux on the same hardware works fine ). Not hardware!

comment:15 by Alexey Kuznetsov, 11 years ago

Freeze under linux too. So it is a CPU issue

Please reopen if still relevant with a recent VirtualBox release.

Same. Been using various virutal box versions without single freeze with i5 4590, 4690k on host with Windows 7 and 10. After upgrade to 11900k and fresh Windows 10 install started to expirience not even freezes, but complete stalls. Windows and linux VMs. Virtualbox 6.1.50, today updated to 7.0.20. Setting machine to pause and unpause kinda helps for a moment, at least i am able to shut down machine. What do i need to submit for debugging?
