Ticket #8852 (closed defect: fixed)
Virtualbox corrupts physical disk when removing snapshot
|Reported by:||rstribrn||Owned by:|
Description (last modified by aeichner) (diff)
- Host: Ubuntu, kernel 2.6.38-9
- VirtualBox is used to boot Windows XP SP3 as guest from physical (raw) device (/dev/sda2)
- Snapshot is taken
- Snapshot has about 4GB after a few days...
- Snapshot remove operation is started...and takes really long time.
1.) Physical device cannot boot as guest anymore
=> Fixed by recreating VMDK for that raw device. => OK
2.) When booting Windows XP as guest, it crashes on corrupted url.dll
3.) When booting Windows XP as host, same behavior
=> When looking at C:\Windows\system32\url.dll, it has some TEXT information => When comparing it with C:\Windows\system32\dllcache\url.dll, its binary..
- both files differs
Both files has same length => First one is clearly corrupted.
4.) Since Windows XP was able to boot without problems before I removed the snapshot, it's clear that VirtualBox is responsible for that.
Please either disable creating Snapshots for raw physical devices or fix it somehow. :-(
