yes, also with SSD it is possible to hang it in my case, though it
needs quite a lot of workload to happen. also in my case it gets a
bit worse than on ext4 becuase of the CoW nature of ZFS, but it
seems the root cause is overloaded IO.<br>
<br>
IT would be nice to make the guest wait, not to pause the VM, that
would make more sense in this case. though it's true it might not
be implemented ...<br>

<p dir="ltr">Shuttering/hangs usually happen to me if IO
doesnt manage to cope with the load.<br>
When using zfs (zvol) this basically means that I can use
this only on ssd drives.<br>
Can this be the same case? Any ideas how to make the guest
wait for io, not qemu?</p>

<p dir="ltr">What can cause random guest Hang-ups? I
mean totally very short freezes. It can't be the
input pheriphrals, since I am using Synergy. Can it
be CPU related?</p>
