Subject Re: SystemVM (kvm) : 3 different versions for the same CloudStack version (4.5.1)
Date Mon, 25 May 2015 10:56:54 GMT
Hi Milamber,

In theory you should be able to use any of the systemvmtemplates and also from,
but the one I published on is the latest and has the few additional
improvements, latest packages and security updates.

I’ve tested this and it seems to have worked for me on Ubuntu 14.04 based host, can you
share what is your KVM host like, distro, libvirt/qemu version and kernel version? Was the
host Intel-VT or AMD-V enabled, or was it virtualized (KVM on KVM/Xen/VMWare)? What is the
time and timezone on your host and if kvmclock was disable/enabled on the kvm host?

Lastly, can you also share if the SSVM gets stuck indefinitely or you did not wait that long
and decided to reboot it?

Regarding the upgrade path, it does not matter really. Since you register 4.5 template before
upgrading the upgrade path would simply check if a systemvm template exists for currently
used unique hypervisors (it does that by checking for current hosts with distinct hypervisors
from cluster table). The checksums and URLs are in there for adding rows in the db in case
you decide to add a new hypervisor host and it needs to donwload a suitable template for that
new hypervisor. There are on-going discussion on improving the upgrade process so this issue
may be addressed in that.
