<div dir="ltr"><div><div><div><div>Hi all,<br><br></div> I am facing issue with VM launch. I am using openstack <b>Havana.</b> I have one compute node with following specification:<br><br>root@compute-node:~# lscpu<br>Architecture: x86_64<br>
CPU op-mode(s): 32-bit, 64-bit<br>Byte Order: Little Endian<br>CPU(s): 8<br>On-line CPU(s) list: 0-7<br>Thread(s) per core: 1<br>Core(s) per socket: 4<br>Socket(s): 2<br>
NUMA node(s): 1<br>Vendor ID: GenuineIntel<br>CPU family: 6<br>Model: 15<br>Stepping: 7<br>CPU MHz: 1995.104<br>BogoMIPS: 3990.02<br>
Virtualization: VT-x<br>L1d cache: 32K<br>L1i cache: 32K<br>L2 cache: 4096K<br>NUMA node0 CPU(s): 0-7<br><br>root@compute-node:~# free -h<br> total used free shared buffers cached<br>
Mem: 15G 1.5G 14G 0B 174M 531M<br>-/+ buffers/cache: 870M 14G<br>Swap: 15G 0B 15G<br><br><br></div>But I am not able to launch more than 12-14 VM. VM launch fails. Even I don't see <b>ERROR </b>logs in any of nova logs on both <b>openstack controller and compute node.</b> Don't see any request coming to compute node also. I just tailed nova compute logs on compute node. As soon as, I clean the previous VMs , everything works fine. I have never observed this with Grizzly.<br>
