Ticket Resolution Summary Owner Reporter
#12103 fixed Application hangs when using multiple CPUs Bakken
Description

Host is a Dell Latitude E5530 with i5 CPU. I have setup an Arch Linux guest which works fine on a single CPU. If I choose multiple CPUs the guest will run for a while but after an indeterminate amount of time (usually within a minute) the VirtualBox application hangs on the host and has to be forced closed.

#18972 fixed Application windows disappear when switching to Seamless Mode 4til7
Description

When I switch to seamless mode, all application windows disappear. Problem experienced under 6.02. Upgraded to 6.12. The problem still exists.

This may be an ongoing issue. A search of bug track found reports of seamless mode not working (or not working well, e.g. https://www.virtualbox.org/ticket/15318). The ones reviewed were not specific about the issues experienced.

#481 fixed Applications segfaults often on Mandrake Linux 9.2 guest Technologov
Description

hi all !

Mandrake Linux 9.2 guest works :) ! Or kind of works... :(

It's applications segfault very often. Especially "vi". KDE apps segfault sometimes. Kernel (2.4.22) didn't segfault.

Host: Windows XP, VirtualBox 1.4.0 on Athlon XP, 1GB of RAM. Guest: Mandrake Linux 9.2

Mandrake Linux 9.2 download site: (5.7.2007) http://ftp.ale.org/pub/mirrors/mandrake/official/iso/9.2/i586/

Please check it.

Overall, VirtualBox also have similar stability problems with some applications failing on Windows XP guest, such as DOSbox.

See: http://www.virtualbox.org/ticket/241

Related-Offtopic: Is there any *universal* way to make virtualizers stable ? VMware stability is significantly highter than VirtualBox's - that's a fact - but why ? What magic they did on their product ? Can we do the same ?

I thought hardware-virtualization (Vanderpool-capable CPU) is silverbullet, that makes things ultimately stable, but after testing KVM, I know that it's not true. It has it's own share of bugs.

Can I help somehow ?
