Virtualbox corrupts physical disk when removing snapshot
Reported by: | Rostislav Stříbrný | Owned by: | |
---|---|---|---|
Component: | virtual disk | Version: | VirtualBox 4.0.6 |
Keywords: | Cc: | ||
Guest type: | Windows | Host type: | Linux |
Description (last modified by )
Situations:
- 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. :-(
