So: 1. I made snapshot of guest 2. resize snapshot vdi file with {{{VBoxManage modifyhd ~/vb/vm/work/deuter/Snapshots/\{5c558b0f-1ea6-4c48-92e0-9095747529b1\}.vdi --resize 20000}}} 3. tried to resize windows partition on disk. And guest start to behave undeterministic. - with gparted ran in guest I saw a lot disk error messages - windows guest (which normally works in this machine) aborts in random moments Seems that ""use host IO cache"" has some impact on this (witch cache on, machine aborts earlier)" defect new other VirtualBox 4.3.28 other other
