Although the guest resumes and is interactive, it seems that anything involving filesystem operations hang forever and do not return. + +Suspending and resuming the Linux guest seems to work perfectly if I don't suspend/resume the host. + +Ultimately what I'm wanting to do is share the drive between VMs with qemu-storage-daemon. I can reproduce the problem in that scenario in much the same way. Using PCI passthrough with the same VM and device works fine and doesn't exhibit this problem. + +Hopefully that's clear enough - let me know if there's anything else I can provide. +Steps to reproduce: +1. Create a VM with a dedicated NVMe disk. +2. Boot an ISO and install to the disk. +3. Verify that suspend and resume works when not suspending the host. +4. Suspend the guest. +5. Suspend the host. +6. Wake the host. +7. Wake the guest. +8. Try just about anything that isn't likely already cached somewhere: `du -s /etc`. +Additional information: +I've attached the libvirt domain XML[1] and libvirtd debug logs for QEMU[2] ("1:qemu") that covers suspending the guest & host, resuming host & guest and doing something to cause a hang.
