BLKCACHE_IOERR when creating snapshot
Posted: 28. Jan 2011, 10:24
Hi
I am running VirtualBox on a Windows 7 computer, with Solaris 10 as the guest OS. In the beginning everything worked fine, I was able to save the first snapshot. But I can't save a new snapshot, when I try to do it I get the following error:
"The I/O cache encountered an error while updating data in medium "ahci-0-0" (rc=VERR_VD_IMAGE_READ_ONLY). Make sure there is enough free space on the disk and that the disk is working properly. Operation can be resumed afterwards".
I don't know how even how to troubleshoot this. I didn't change any in the configuration of VirtualBox between the snapshots, just was working in the guest OS. I have enough space both on host OS and guest OS. Disks are working properly.
Thanks in advance.
Kind regards,
Andreas
