segfault in VBoxHeadless 4.1.2 while doing clonehd — at Version 5

Reported by: kerlerm Owned by:
Component: VMM Version: VirtualBox 4.1.4
Keywords: crash clonehd segfault 4.1.2 Cc:
Guest type: other Host type: Linux

Description (last modified by Frank Mehnert)

Hi!

I was executing a "clonehd" command. While the system was under that load a segfault occured in VBoxHeadless. Host is a FC15 X64 system with several guest on it. Linux guests showed ATA bus resets when the error occurred, some windows guests were aborted.

I wonder if this line in the logs might be connected with that? EXT4-fs (dm-2): Unaligned AIO/DIO on inode 12845094 by VBoxHeadless; performance will be poor.

The same configuration worked flawlessly with FC12 - VBox 3.2.12

Any hints / workarounds? Thanks a lot!

Cheers Martin

Today I updated to vbox 4.1.4. Same problem persists. Guests get randomly aborted - not only while the server is under high load. Seems to be connected to bug ticket no. 9661: https://www.virtualbox.org/ticket/9661
