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. I tried to leave enough time afterwards for any timeout to occur. - -1. [nvme-voidlinux.xml](/uploads/1dea47af096ce58175f7aa526eca455e/nvme-voidlinux.xml) -2.
