Issues with running solaris VM over kvm

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hey,

I'm trying to run Solaris 11.2 over x86 centos host:
Versions:
qemu-kvm-1.5.3-126.el7_0.5.strato.c89c981.x86_64
kernel 3.10.0-514.10.2.el7.x86_64

Have 2 issues:
1. After a while the vm just stuck. Have no idea why. Tried some
poweradm configurations - but didnt manage to solve anything. The
period it take to the vm to get stuck is related to the numbers of the
cpus defined for it - with 16 it takes ~3h, with 2 it takes ~48h.
2. I have issues with exposing the correct number of vcpus to the
guest. For some reason, it maps sockets to cpus (8 sockets in libvirt
becomes 8 cpus in the solaris vm). But it's limited by 16. If I define
32 sockets, the vm see only 1 cpu, but does see all the 32 sockets.

Any help will be very appreciated.

Thanks,
Rom
