Tashkinov,,"Currently you cannot attach a full raw real harddisk with the RDONLY (read-only) flag set as the VM execution runs into an error: '''The I/O cache encountered an error while updating data in medium ""ahci-0-1"" (rc=VERR_INVALID_HANDLE). Make sure there is enough free space on the disk and that the disk is working properly. Operation can be resumed afterwards.''' {{{ Error ID: BLKCACHE_IOERR Severity: Non-Fatal Error [Copy] [OK] }}} Pressing OK doesn't allow to continue the execution. Please fix. Here's an example VMDK image: {{{ # Disk DescriptorFile version=1 CID=abcdedfg parentCID=ffffffff createType=""fullDevice"" # Extent description RDONLY 800000000 FLAT ""/dev/sda"" 0 # The disk Data Base #DDB ddb.virtualHWVersion = ""4"" ddb.adapterType=""ide"" ddb.geometry.cylinders=""16383"" ddb.geometry.heads=""16"" ddb.geometry.sectors=""63"" ddb.uuid.image=""xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"" ddb.uuid.parent=""00000000-0000-0000-0000-000000000000"" ddb.uuid.modification=""xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"" ddb.uuid.parentmodification=""00000000-0000-0000-0000-000000000000"" ddb.geometry.biosCylinders=""1024"" ddb.geometry.biosHeads=""255"" ddb.geometry.biosSectors=""63"" }}}",defect,new,other,,,,,all,all
