Does reverting the commit suggested in comment 2 work for you ?

Since commit 1d4e7e3c increased "struct kvm_memslots" size from order 2 to
order 4, like-hood of above failure grew in ~2x times (there where 90 order 2
free pages)
Looking at log from comment 1
allocation failure shouldn't happened since there are still 40 Order 4 free
pages:
> úno 13 18:10:27 argus kernel: Normal: 18555*4kB (UEMC) 145*8kB (UMC) 92*16kB (UM) 54*32kB (UM) 40*64kB (UM) 9*128kB (UM) 2*256kB (U) 0*512kB 0*1024kB 0*2048kB 0*4096kB = 82804kB
Anyway I'll post patch that changes allocation vmalloc-ed memory as quick fix
and look for possibility of allocating actual amount of slots instead of
possible maximum like it's done now.

Hello.
After reverting commit 1d4e7e3c0bca747d0fc54069a6ab8393349431c0 i had no
problem any more. But we have to keep in mind this error only happend now and
then. Especially creating snapshots of running vm's triggered the error but
this runs without crashing the vm now. I tested it a few times.
cheers

Could you try following patch without reverting 1d4e7e3c0bca ?

Hello.
I applied the patch to vanilla 3.19.2. No problems so far. Did a few snapshots
and vm restarts.

Nope,
I've posted v2 of the patch fixing problems Marcelo pointed out:
https://www.marc.info/?l=kvm&m=142685412907951&w=3
so it' needs to be reviewed/tested.
