virtualbox.org

I have VitrualBox 4.2.4r81684 on Windows 7 32-bit with last updates.
I tried to install and run Win 2k8r2 and RHEL6 x64 as guest OS and my host OS restarts (reboots) automatically after sometimes guest system is running.
In this moment I don't get BSOD.
And host OS also does not create a minidump file.
I attach an attachment file with log guest OS after the collapse.

Please, help me for this problem.

You probably need to turn on IO APIC.

Also, 700MB seems a tad hopeful for a 64bit guest OS, though I haven't checked what RedHat's min requirements are.

mpack, thanks for answer. I will try it when I get the laptop.

I tried set size of memory over 1024 Mb, but I have this problem.

P.S. VirtualBox was installed on HP EliteBook 8440p

Yes, your host only has 1500MB or so available, so allocating more to the VM would be a problem. That doesn't change what I said earlier though. Basically, if you want to run these resource hogging guests then you need more resources.

VirtualBox crashed again with host OS.
I set checkbox IO APIC to Enable. I start guest RHEL. System rebooted again.
I set memory to 1048 Mb with IO APIC enable. I start guest RHEL. System rebooted again.
In all reboots host OS was have free memory over 500Mb.
First log in attached - IO APIC Enable and memory ~700Mb.
Second log in attached - IO APIC Enable and memory ~1048 Mb.

RHEL don't have any services. This is clear OS and no many memory or CPU or other utilization.

May be in VBox has a debug mode? But I do not know how to turn it on ...

Why would a slightly RAM-starved clean guest OS cause the host OS to freeze/lockup/whatever ?

@ Mc.Sim
Are you sure your hard disk where your VM images are is reliable ?

AnotherLife, thanks for right way.
Today I started Victoria 3.52 and found 1 bad block.
I fixed this error and Virtualbox no more reboots.
I will watch him work....

Start backing up your stuff, because it may suddenly become unbootable ...

I like Support HP. ))
I get new HDD by DHL in two work day!!! Very good

I'm having the same issue on my lenovo edge11 laptop after adding another 2GB ram to it.

My laptop is running win7 pro 32bit version with 2GB ram at first, and i installed both win7 ultimate 32bit & 64bit VMs to it.

Both VMs are running just fine until i added another 2GB ram to it. After the upgrade when ever i tried to start the 64bit guest, my laptop reboot.

The 32bit guest run fine tho.

Any ideas??

Thank you.

vm log attached.

errr, just ran the test for an hour, no error found...

Today I get reboot again.
With new hard disk. With all correct work equipment.

Symptoms reboot: at any moment the laptop freezes, then the screen goes black and the speakers rattle 1-2 seconds. Immediately after that, the laptop is turned off and - starts.

Your log is truncated, zip it before attaching it
