I did the original work using AFL to fuzz qemu-img and find
problematic images. From that work Dan & I suggested some fairly low
limits (10 seconds IIRC). See:

A lot more problematic images were found (at

This is the code in libguestfs if you prefer something in C:
https://github.com/libguestfs/libguestfs/blob/3a87c4bb441430c9cef9223e67d10bf51a4e865c/lib/info.c#L150-L160

hi,
I try to experiment LinuxTerminalServerProject on qemu virtualization
I installed ltsp on a ubuntu-1804 (virtualized) and run:
qemu-system-x86_64 -enable-kvm -m 1500 -hda /.../ubuser-18.img -k en-us -net
nic,vlan=0 -net tap,vlan=0,ifname=tap0 -k en-us -boot c -usbdevice mouse

Is there any possibility of doing this? I realize that suspending is not
possible with PCI devices attached, but would it be possible to instead
automate the process of hot removing all the PCI devices first, then
suspending, then hot adding them back again when resuming the machine? That'll
