Re: [libvirt] [Qemu-devel] incorrect memory size inside vm
Hello.
Actually it was my mistake.
After some time using memory in guest (find /, cp bigfine, etc), res
size of qemu process shrinks to expected value.
Sorry for disturbing.
Now i don't see any memory waste in guest and host when using 'base'
memory + 'dimm' memory.
Although i have one issue.
When i start qemu via libvirt with 16GB mem and 1G current mem:
(...)
<memory unit='KiB'>16777216</memory>
<currentMemory unit='KiB'>1048576</currentMemory>
(...)
Qemu starts, and balloon can't free memmory, so guest doesn't boot (It
hangs or is looped in ' virtio_balloon virtio2: Out of puff! Can't get 1
pages').
I think this is because dimm memmory is not yet onlined, and balloon
already tries to shring memory in guest.
Best regards

Would you mind to share you argument set to an emulator? As far as I
understood you are using plain ballooning with most results from above
for which those numbers are expected. The case with 5+gig memory
consumption for deflated 1G guest looks like a bug with mixed
dimm/balloon configuration if you are tried against latest qemu, so
please describe a setup a bit more verbosely too.
