Sooo... here is my experience: if using correct VirtIO OS TYPE (set on template/VM) - i.e. ubuntu 14.04, Centos 6.x or 7.x, Windows PV, other PV (but NOT centos 6.0 or 7.0 - these "dot zero" versions are NOT virtio at least in ACS 4.8), then when VM is STARTED FROM ACS (power on VM) - all drives should be attached as VirtIO.
BUT if you do same as above, then additionally create and HOTPLUG new drives/volumes to KVM - it will be IDE - some strange default behavior during hotplug action.... just stop VM/start and it will become VirtIO again... In order to "troubleshoot" these instances - you need to be careful to which OS TYPE was the instance set to (this is inherited from TEMPLATE, if you used some template - but it CAN be changed on an deployed&&stopped instance) In case you plan to i.e. move your Windows instances from IDE to VirtIO - be aware that it might fail miserably, and OS will fail to boot - but there is a fix with *"* bcdedit /set detecthal boolean (where boolean is one of 1, on, yes or true) " after which Windows will detect HAL again and boot just fine. Let me know if more help needed Cheers On Thu, 20 Sep 2018 at 11:22, Adam Witwicki <awitwi...@oakfordis.com> wrote: > > > It looks like I can just add > > rootDiskController virtio > > To the templates settings tab? > > Can anyone confirm? > > Thanks > > Adam > > -----Original Message----- > From: Ivan Kudryavtsev <kudryavtsev...@bw-sw.com> > Sent: 20 September 2018 10:20 > To: users <users@cloudstack.apache.org> > Subject: Re: Disk controller type > > ** This mail originated from OUTSIDE the Oakford corporate network.
