Andrija Panic commented on CLOUDSTACK-8353:
-------------------------------------------
I saw that part of code earlier, but this again doenst solve the issue - it
references only "Windows 2008" as guest OS, not "Windows PV" - and to be honest
no-one probably uses "Windows 2008" as OS type, because its not virtio (we are
on KVM) - and also code only references (if I read code correclty, Im not
developer) only centos 6.5 and 7, not i.e. Ubuntu as host etc.
We have actually develop solution internally, similar code (and NOT yet
tested(, but we are not checking host OS in the code (we assume all hots
support hyperv enligment flags), so not sure if this is convinient for
commnunity (if it passes our internal tests first...)
I will try to update here, or have one of our devs comment after we do some
testing.
