The vultr install does indeed disable virtio-random, but that wasn't the on= ly issue: I created my own ISO without virtio-random , and whilst it stopped t= he boot hang, it still caused problems (hanging on reboot being one) I talked with the vultr guy and he confirmed - he had to disable virtio-ran= dom AND change the KVM profile to boot : > "2021-07-14 16:37:43 > We've found that v12 and older of FreeBSD do not actually support q35 - s= o when any version of FreeBSD is selected from our control panel we default= that back to i440fx. We do have a few customers using the iso-over-image t= rick, and we didn't want to break them if they're just selecting the defaul= t version (13) and then trying to install 12 over it. > We have not done extensive testing of FreeBSD on q35 yet - it seems like = support for this is very new, so I wouldn't be surprised if there were stil= l issues causing it to hang at reboot. >Brian, Vultr.com Support " --=20 You are receiving this mail because: You are the assignee for the bug.
