Storage systems disconnecting randomly.

Reported by: daan Owned by:
Priority: major Component: virtual disk
Version: VirtualBox 3.2.6 Keywords: vdi lvm vmdk sata storage freezing
Cc: Guest type: Linux
Host type: Linux

Description (last modified by aeichner) (diff)


Server installation of VirtualBox PUEL on SunFire x2270

CPU: Intel Xeon E5504, 2.00GHz (64bit) Storage: 2 SATA disks, RAID1 (root partition); 3 SATA disks, RAID5 (data partition) OS: CentOS 5.5


Various 64bit linux distributions - CentOS 5.5 (just the same image as host), Fedora 13, Arch Linux.

CPU: added one or two cores, IO/APIC enabled, EFI disabled, PEA/NX disabled, VT-x enabled, Nested Paging enabled

RAM: 2048MB

Storage: SATA controller (AHCI), standard 150GB *.vdi on xfs physical filesystem., host IO caching disabled, dm_crypt/luks encrypted /home partitionm ext3 filesystem

Network: bridged Pc-NET III fast

Linux guest is accessed through the VRDP connection.


After accessing the destkop, system is randomly freezing. Networking still works, I can ping the machine, but SSH won't give me shell after logon. I can click on some running apps (probably cached in RAM) but I am not able to work with them. It seems like the VDI disk was completely disconnected from virtual machine.

I did few tests.

=> disabled dm_crypt/luks encryption => changed standard vdi disks from xfs physical filesystem to logical volumes with RAW vmdk abstraction => changed host OS from CentOS to Arch Linux => changed virtualbox from centos rmp package => changed virtualbox "all distribution" binary => changed virtualbox compiled from ArchLinux user repositury

And remote virtual desktop is still getting frozen in the same way.

Logs says nothing, I went through vbox.log, dmesg, messages.log, kernel.log, syslog, faillog - nothing relevant at all.

Chance is that the fixes to the virtual SATA controller which went into 3.2.8 are addressing those issues...

well, unfortunatelly, problem remains. i've tried also ide controller with *.vdi images and got the same results.

in order to really exclude some kind of hardware issue, i've installed vbox puel *.deb package on completely different machine (with debian seystem.)

after some hours of remote work - dstat no longer made any record of machnine's activity.

Looks like i've running in a similar problem.

Using VB on mac osx. Every time I changing e.g. the network source (from bridge to nat) the storage get disconnected. (AHCI#0: Port 0 reset) Same thing happens randomly with usb connections.

Occurred on latest 4.3 and on 5.0
