The problem with this theory is we are passing the
VIR_DOMAIN_DESTROY_GRACEFUL flag, so that would indicate that this
flag is buggy.
I think what we need is a test case, so here goes. Note you must run
these steps as *non-root*.
(1) Download the attachment to /var/tmp
(2) chmod +x /var/tmp/qemu.sh
(3) killall libvirtd ;# kills the session libvirtd
(4) LIBGUESTFS_HV=/var/tmp/qemu.sh guestfish -N fs exit -vx
You should see at the end of the output:
libguestfs: calling virDomainDestroy "guestfs-q94hsiz89t8jp418"
flags=VIR_DOMAIN_DESTROY_GRACEFUL
[pause of a few seconds]
libguestfs: error: could not destroy libvirt domain: Failed to terminate process 11412
with SIGTERM: Device or resource busy [code=38 domain=0]
If someone else can reproduce this, then I will file a bug.
Yep, I could perfectly reproduce your test case (thanks for constructing
that):
$ LIBGUESTFS_HV=/var/tmp/qemu.sh guestfish -N fs exit -vx
[...]
fsync /dev/sda
guestfsd: main_loop: proc 282 (internal_autosync) took 0.00 seconds

Upstream OpenStack Nova employs a similar suggestion (calling the
virDomainDestroy() API about 3 more times) proposed by Dan in this
thread:
