Guru meditation

[palmoreck]

I suspended my laptop while running a virtual box machine of linuxmint on Windows 8

After one or two hours i reboot my lap and i got the message of guru meditation.

I dont know what happened and its very important to recover my files

Any solution?

its very important to recover my files. Any solution?

Restore from a backup?

Where is the guru meditation? Host or guest? Minimum information needed for assistance.

[palmoreck]

VirtualBox VM 4.2.6 r82870 win.amd64 (Dec 19 2012 14:42:41) release log

You're running a way too old version of VirtualBox. Try to upgrade to the latest.

00:00:01.344957 Host RAM: 6029MB total, 2802MB available
00:00:01.574664   RamSize         <integer> = 0x0000000100000000 (4 294 967 296, 4 GB)

Do you see the humongous problem here? (hint: you can't give what you don't have)

00:00:01.574656   NumCPUs         <integer> = 0x0000000000000004 (4)
00:00:01.915605 Logical host processors: 4 present, 4 max, 4 online, online mask: 000000000000000f

Although the VBox log doesn't specifically state, I believe that you have 2 physical CPUs, which translates to 4 logical CPUs, which you assign all to the guest. What's going to be left for the host?

OLD LOG: 00:00:01.803581 File system of 'D:\LMint\LMint.vdi' is ntfs
NEW LOG:

Did you miss your D:\ drive? In fact there is no "HD" in your VM!

I've been working with that version of Vbox and with the Ram and cores that appears in the log and i haven´t any problem until now.

Perhaps in one moment i've changed the D:\ and didnt notice

I reduced the Ram and cores and fix the drive D:\ but i got the same problem.

I´ll try to upgrade to the latest version.

Also since i got the problem i made a backup of the virtual machine (.vdi and .vbox) in my external hard disk and i was thinking of installing virtualbox in other lap and create other .vbox but with the copy of my .vdi ¿Is possible that i can work again with my data that i have in my .vdi with different .vbox? ¿or is there any option to change the configuration file (.vbox) that work with my .vdi?

Thanks for your answers¡

[palmoreck]

Upgrade was the solution!

Thanks a lot!

The rest of the points are still valid. You should not overcommit memory or CPUs. Fix those or face problems later...

Although the VBox log doesn't specifically state, I believe that you have 2 physical CPUs

Yep, dual core: Intel(R) Core(TM) i5-3317U CPU @ 1.70GHz.

Strangely, VBox does have a physical cores counter later, but shows it as 0. Mind you, ISTR the feature was only added around 4.2.x, so later bug fixes are to be expected. Or it could be a symptom of :

03:31:29.028132 !! Guru Meditation -4011 (VERR_VMX_IN_VMX_ROOT_MODE)
03:31:29.249829 !!

Which is saying that something else was already using VT-x.
