I tried the following per your suggestion: 920 qemu-nbd --persistent -p 2000 /root/qemu/q1.img & 921 nbd-client -persist localhost 2000 /dev/nbd0 922 fsck /dev/nbd0 923 mount /dev/nbd0 /mnt 924 ls /mnt 925 umount /dev/nbd0 :: 927 echo reboot >/sys/power/disk 928 echo disk >/sys/power/state 929 mount /dev/nbd0 /mnt This seems to work; that is both sides (client and server) persist after the hibernate cycle. However, if I don't 'umount' '/dev/nbd0' before the hibernate cycle, and try to 'ls /mnt' after, the 'ls' hangs indefinitely. For my real use case we have the root filesystem mounted, so unmounting is not an option (at least I don't think so). I also tried remounting readonly, and also 'blockdev --flushbufs ..' before the hibernate cycle -- either or both did not help. I had thought about trying a 'chroot' and then a 'umount', but have not yet tried this. This one was so close.. Thank you for all your attention on this.
