Martins Jakubovics commented on CLOUDSTACK-6928:
------------------------------------------------

I can confirm this, have same issue. Also, if compute offering is changed from non limited
compute offering to offering with limits, new limits is not applied on instance (on root disk)
reboot don't help also.

KVM Host - Ubuntu 14.04.3 LTS
