Ticket #9749 (closed defect: fixed)
useHostIOCache does not automatically turn on for some vm's
|Reported by:||Spyplane||Owned by:|
I've had several guest vm's have severe filesystem corruptions. I found today that my problems might be due to useHostIOCache being set to False on all of my vm's. I only use vboxmanage, instead of the UI, so I don't get the warnings regarding ext4, linux and not having useHostIOCache enabled. After talking to 'aeichner' on IRC, he mentioned that vbox should be automatically enabling it in my version of virtualbox (4.0.12), but after checking my logs, this is not the case. I've attached the logs of one vm that has had inode errors and still has useHostIOCache set to false in the .vbox files.
I've had this issue on 6 identical servers running Ubuntu Server 11.04 64bit, with a variety of virtualbox vm's. I've had FS corruption on 15+ vm's.
