#2368 fixed Guest time of day not updated when resuming from a saved virtual machine Robert Krawitz
Description

If I save and then resume a guest, the time of day is not updated in the guest. It continues from the point at which I saved the guest. So if I save the guest at noon, and then resume it at 6:00 PM, the guest still thinks it's noon.

I am running ntpd on my host. I have the guest configured to use the host (10.0.2.2 -- using NAT networking) as a time server, and I manually resync the time, it fixes up the time. My understanding is that the guest additions are supposed to reset the time when a machine is resumed.

Host is OpenSUSE 11.0.

Guest is OpenSolaris (currently at onnv_98, but this behavior isn't new). Using Guest Additions that came with 2.0.2.

#2369 worksforme No sound for linux host when VM running Dario
Description

After I start an XP VM on a linux host (Gentoo amd64, kernel 2.6.26-r1) all applications using alsa complains about /dev/dsp not available (VBox is using it but dowsn't let anyone else grab it).

Applications started *BEFORE* VM starts can still reproduce audio (so can VM).

I just opened xine and could play with audio an video with MPEG2 audio, but another with A/52 5.1 audio complains about /dev/dsp busy.

#2370 fixed Memory leak with Solaris Host for 2.0.2 => Fixed in 2.0.6 Dan Jones
Description

HostOS: SunOS jcc-one 5.10 Generic_137112-07 i86pc i386 i86pc
GuestOS: OpenSolaris 200805

I start off with the long term stable memory usage of

jcc-one> memcheck
Total memory = 3068 MB
 Used memory = 1652 MB
 Free memory = 1416 MB
jcc-one>

Then I fire up VirtualBox and after a couple of minutes it settles to look like this

jcc-one> memcheck
Total memory = 3068 MB
 Used memory = 2460 MB
 Free memory = 608 MB
jcc-one>

which is what I would expect given the 1024MB memory size configured in VirtualBox.

Let the system sit idle for about 6 hours and we get

jcc-one> memcheck
Total memory = 3068 MB
 Used memory = 2796 MB
 Free memory = 272 MB
jcc-one>

and if I let it continue on for another 6 we hit the death of swap city.

FYI - memcheck is this simple beastie that I wrote long ago to track database thrash on a large web site:

jcc-one> cat memcheck.c
#include <stdio.h>
#include <unistd.h>
void main ()
{
        long total;
        long free;
        long page_size;

        /* convert pages to kilo-pages */
        total = sysconf(_SC_PHYS_PAGES) / 1024;
        free = sysconf(_SC_AVPHYS_PAGES) / 1024;

        /* convert page size to KB */
        page_size = sysconf(_SC_PAGESIZE) / 1024;

        total *= page_size;
        free *= page_size;

        printf ("Total memory = %ld MB\n", total);
        printf (" Used memory = %ld MB\n", total - free);
        printf (" Free memory = %ld MB\n", free);

        exit(0);
}
