Guests not starting after upgrd. (1.4->1.5) => Fixed in SVN / 1.5.2

[kaasgaard]

After an upgrade from 1.4 to 1.5 (rpm version) I am no longer able to start my machines.

I get the following error: Failed to open release log (, VERR_NO_MEMORY).

Result Code: 0x80004005 Component: Console Interface: IConsole {1dea5c4b-0753-4193-b909-22330f64ec45}

Fedora 7, x86_64, kernel 2.6.23

Nothing else changed other than the upgrade, and the previous version (1.4) worked perfectly.

Plenty of memory left as well: Mem: 2037128k total, 1051656k used, 985472k free, 28468k buffers Swap: 4096532k total, 0k used, 4096532k free, 502804k cached

Strange problem. Could you try to start your virtual machine with the following commands:

strace -f -s512 -o ~/VBoxSVC.log /usr/lib/virtualbox/VBoxSVC &
strace -f -s512 -o ~/VBoxSDL.log /usr/lib/virtualbox/VBoxSDL -vm <vm_name>

and attach both log files?

VBoxSVC.log

VBoxSDL.log part 3

[kaasgaard]

Hi

VBoxSDL.log

has been splitted into 3 files due to upload file size limitations

Martin

[Frank Mehnert]

Thanks Martin for that report. It turned out that an mmap(..., MAP_ANONYMOUS, ...) call failed for some reason with -EPERM. Are there any entries in /var/log/kern.log or security-related log files regarding VirtualBox?

[kaasgaard]

Hi

No /var/log/kern.log on fedora 7. /var/log/messages & /var/log/security are empty

But /var/log/audit/audit.log has the following:

type=AVC msg=audit(1189452856.148:123): avc:  denied  { execmem } for  pid=26784 comm="VirtualBox" scontext=system_u:system_r:unconfined_t:s0 tcontext=system_u:system_r:unconfined_t:s0 tclass=process

Seems like it's selinux related?

Martin

[Frank Mehnert]

Yes, it is. Did you change any SELinux settings? I have Fedora7 x86-64 here and the SELinux setting 'Allow unconfined executables to map a region as both executable and writable...' is checked here. Did you change that setting? VirtualBox depends on this to work properly. I'm sure that, for instance java, depends on this setting as well.

[Frank Mehnert]

Could you try

chcon -t java_exec_t /usr/lib/virtualbox/VirtualBox

[kaasgaard]

Hi,

chcon made it work like a charm.

Didn't even think of that myself, since it was a "pure" upgrade.

Thanx a bunch.

Martin

[Frank Mehnert]

This fix is included in the next bugfix release which is expected within a few days.
