8221	BLKCACHE_IOERR after creating snapshots. => fixed in svn/4.0.4	jptech		"I get a BLKCACHE_IOERR after creating a 2nd snapshot on one of my VMs.  It causes the VM to switch into suspended state when trying to boot the guest.  Others have reported a similar problem here:

http://forums.virtualbox.org/viewtopic.php?f=6&t=38523

Some things that may be relevant:

 * The VM was imported from an appliance that I created (VMDK disk)
 * Everything works ok if I enable '''Use host I/O cache''' on my VM
 * I'm using an AHCI SATA controller in my VM.

I experience this problem by doing the following:

 * create a minimal guest installation
 * export the guest as an appliance
 * import the appliance as a new VM
 * work on guest
 * stop guest
 * snapshot 1
 * start guest
 * work on guest
 * stop guest
 * snapshot 2
 * error starting guest

I'm using a Windows 7 64bit host and an Ubuntu 10.04.1 (i386) guest.  All of my virtual machine disk files are writable and I have >150GB free on the (host) disk."	defect	closed	other	VirtualBox 4.0.2	fixed			Linux	Windows
