--- Comment #6 from Igor Mammedov <imammedo@redhat.com> ---
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.
