Ticket #8643 (closed defect: fixed)
memory corruption in linux guest => Fixed in SVN
|Reported by:||ralfw||Owned by:|
When running 64bit linux guests with more than 2g of ram on a windows vista or windows 7 host the memory of the guest is corrupted sometimes.
I can check the corruption with the "memtester" tool from Charles Cazabon ( the two guest systems i tested, Gentoo and Ubuntu 10.10, both have packages for this ) and trigger it by switching terminals in gentoo from the framebuffer console ( alt-f2, alt-f1, memory corrupted ) or just let the memtester program run in ubuntu and wait a for some time. Note: memtester has to test almost all available memory.
The corruption always happens at an offset of 0x458 from a page start with a 64bit value of 0x100500000 being somewhow written to the memory address.
This happens with and without guest additions and on the amd-v and intel vt-x platforms i have access to.
I'll attach the Vbox.log of the gentoo guest.
