Resume fails since 4.3.16 on Ubuntu 14.04 Host for Windows 7 Guests: Failed to load unit 'pgm' (VERR_NO_MEMORY)

[g2flyer]

Since 4.13.16 and all subsequent versions to 4.3.26 windows VMs fail to resume with following error

Failed to open a session for the virtual machine Win7 KVM. Failed to load unit 'pgm' (VERR_NO_MEMORY). Result Code: NS_ERROR_FAILURE (0x80004005) Component: Console Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

It is not only after an upgraded, but also subsequently. It doesn't happen all the time, though. It seems it happens only after a VM has run for some time. Changing the VMs RAM settings doesn't seem to make a difference.

My host is a (32-bit!) Ubuntu 14.04 with various kernels; note that reverting to 4.3.14 each time made the problem disappear, so it is unlikely a kernel problem or alike.

Are you sure that the same problem happens if you decrease the VM RAM size to 1GB or 1.5GB? 2GB on 32-bit (as I saw in some of the logs) is quite near to the Limits...

[g2flyer]

Yes, reducing the VM RAM even by 1 GB does not fundamentally help. Note i do have 32-bit PAE and with 3.14 i easily could have VMs with 3.5GB RAM ...

[g2flyer]

BTW: what i forgot to write above: the guests are 64-bit ...

Trying out 5.0 Beta 1 i got first a similar error. Eventually i figured out at least in 5.0 i can avoid (at least in the last 7 suspend/resume cycles :-) the problem if i reduce drastically the amount of RAM associated with the display (i think i had for some some earlier >128 and now set it to 32MB) ....

Log of ubuntu 12.04 failing on 5.0 Beta 2

[g2flyer]

Aargh, on 5.0 Beta 2 i got now the error (see attached log-file) also for an (64-bit) Ubuntu 12.0.4.5 client which had only 12MB of Video RAM. What was strange, though, in this case was that i had the VM running while the laptop went through a suspend/resume cycle and once resumed the VM was also in a bit a funky state as with htop on the host i saw the VMs 4 cpus all with 100% system time and the Guest inside the UI was not responsive. Not sure whether that is really relevant as this was never the case in other VERR_NO_MEMORY problems ...

Problem also happens with 4.3.28 ...

I'm running into the same problem. 64 bit guest on a 32bit host. Failed to load unit 'pgm' (VERR_NO_MEMORY).

Curious observation with the release version of 5: I still got the problem for the ubuntu VM -- the Win 7 VM doesn't boot at all anymore on 5.0 due to some ​update problem .. -- but i could it now at least once overcome by booting the VM in headless-mode!

BTW: above mentioned update problem is also a 32-bit-host-only problem (see ​https://forums.virtualbox.org/viewtopic.php?f=1&t=68786&start=45#p329223), so might actually be related to this problem ...
