*Subject:* [Openstack] New instances booting time
Hello, guys, I have a question
We now have OS Kilo + KVM+ Ubuntu 14.04
Nova-compute.conf:
[libvirt]
virt_type=kvm
images_type = lvm
images_volume_group =openstack-controller01-ky01-vg
volume_clear = none
the problem is when nova boots a new instance it’s SUPER slow
exactly this step:
Running cmd (subprocess): sudo nova-rootwrap /etc/nova/rootwrap.conf
qemu-img convert -O raw
/var/lib/nova/instances/_base/999f7fff2521e4a7243c9e1d21599fd64a19b42e
/dev/openstack-controller01-ky01-vg/5f831046-435c-4636-8b71-a662327b608c_disk
Well, I understand what this step is doing – it’s copying raw image to lvm.
How can we speed it up?
I don’t wanna have instance from 100GB image booted for 4 hours
Don't use base images that are 100G in size. Quite simple, really.
Best,
-jay
