#2472 fixed Display mangles and Windows XP guest freezes Jeenu V
Description

I'm running Windows XP guest on an Ubuntu host with Virtual box 2.0.2. I've installed guest additions, and after that I occasionally get the display mangled (mostly black and with some random colors), and the guest won't resume functioning. Unfortunately I don't know how to reproduce it. However I've noticed that this is mainly observed after some user interaction -- say I moved in/out of the full-screen.

#2473 fixed Assertion failed in PGMAllPool.cpp(1517) int pgmPoolMonitorInsert(PGMPOOL*, PGMPOOLPAGE*) rc=-1701 vondralbra
Description

A 1.5GB RHEL5 guest crashes on a 4GB Host using Ubuntu Intrepid (Kernel 2.6.27-7) during an Oracle installation in the guest machine.

The location of the crash is in pgmPoolMonitorInsert() and the errorcode is -1701(VERR_MM_HYPER_NO_MEMORY) which means that a call to MMHyperAlloc() was not able to allocate any memory although enough cache and swap is available.

There has been some discussion on the issue in the virtualbox-forum in that link: http://forums.virtualbox.org/viewtopic.php?t=10710

The assertion which failed is located here in line 1517 of PGMAllPool.cpp:

   1509         rc = PGMHandlerPhysicalRegisterEx(pVM, PGMPHYSHANDLERTYPE_PHYSICAL_WRITE,
   1510                                           GCPhysPage, GCPhysPage + (PAGE_SIZE - 1),
   1511                                           pPool->pfnAccessHandlerR3, MMHyperCCToR3(pVM, pPage),
   1512                                           pPool->pfnAccessHandlerR0, MMHyperCCToR0(pVM, pPage),
   1513                                           pPool->pfnAccessHandlerGC, MMHyperCCToRC(pVM, pPage),
   1514                                           pPool->pszAccessHandler);
   1515         /** @todo we should probably deal with out-of-memory conditions here, but for now increasing
   1516          * the heap size should suffice. */
   1517         AssertFatalRC(rc);

which means that "rc" is set by either a call to MMHyperAlloc() or a call to pgmHandlerPhysicalSetRamFlagsAndFlushShadowPTs() in PGMAllHandler.cpp

The error occurs on the guest regardless of the size. I tried 900M, 1024M and 1536M.

Very likely this ticket might be a duplicate entry to http://www.virtualbox.org/ticket/1629 but here is no USB-logic involved at all.

#2474 invalid Host Interface Network Connection Deteriorates on Ubuntu Guest with Static IP on OpenSolaris Host. Brian Leonard
Description

I have an OpenSolaris host, configured with static IP address 10.0.1.175, running Apache.

I have an Ubuntu 7.04 guest configured with host interface networking.

From Ubuntu, I can open Firefox and open a web page served from OpenSolaris. However, after a couple of page refreshes, the connection breaks, and Firefox returns with "Failed to Connect"

Even stranger is that the only way I know how to get the guest connection working again is to reboot the host (OpenSolaris). Presumably, there must be some zombie process I could restart to restore the connection, but even if so, it would only be temporary.

Note, this problem does seem to be guest specific, because the connection works fine for me from WindowsXP. I haven't yet tried any other guests, but I'm open to suggestions if some are some known to be more robust than others.

On the Ubuntu guest, the problem is easily repeatable. Note, this problem only occurs when OpenSolaris is configured with a static IP address. When OpenSolaris is configured with DHCP, everything works fine.

Nothing jumped out at me in the log, but it's attached.
