What were you trying to do that didn't work?
Qemu hang when quit dst vm after storage migration(nbd+tls)
Please provide the package NVR for which bug is seen:
kernel version: 5.14.0-427.4.1.el9_4.x86_64
qemu-kvm version: qemu-kvm-8.2.0-9.el9_4
How reproducible:
100%
Steps to reproduce
Create tls env before test:
a. on both server and client, create tls dir for qemu
(server)# mkdir -p /etc/pki/qemu
(client)# mkdir -p /etc/pki/qemu
b. Create keys/cert on server
#cd /etc/pki/qemu
#certtool --generate-privkey > ca-key.pem
#cat ca.tmpl
cn = $hostname_server
ca
cert_signing_key
# certtool --generate-self-signed --load-privkey ca-key.pem --template /root/ca.tmpl --outfile ca-cert.pem
# certtool --generate-privkey > server-key.pem
#cat server.tmpl
organization = GnuTLS test server
cn = $hostname_server
tls_www_server
encryption_key
signing_key
dns_name = dell-per440-08
ip_address = 10.72.140.36
#certtool --generate-certificate --load-privkey server-key.pem --load-ca-certificate x509-ca.pem --load-ca-privkey ca-key.pem --template server.tmpl --outfile server-cert.pem
#scp ca-cert.pem ca-key.pem root@$ip_client:/etc/pki/qemu
c.Create keys/cert in client
#cd /etc/pki/qemu
#certtool --generate-privkey > client-key.pem
#cat client.tpml
cn = $hostname_server
tls_www_client
encryption_key
signing_key
ip_address = $ip_server
dns_name = $shortname_server
#certtool --generate-certificate --load-privkey client-key.pem --load-ca-certificate x509-ca.pem --load-ca-privkey ca-key.pem --template client.tmpl --outfile client-cert.pem

3. In dst, add tls creds, start nbd server and expose image
{"execute": "object-add", "arguments": {"qom-type": "tls-creds-x509", "id": "tls0", "dir": "/etc/pki/qemu", "endpoint": "server", "verify-peer": true}, "id": "ZLsQepWJ"}
{"execute": "nbd-server-start", "arguments": {"addr": {"type": "inet", "data": {"host": "$ip_dst", "port": "3333"}}, "tls-creds": "tls0"}, "id": "HuJrJqKc"}
{"execute":"block-export-add","arguments":{"id": "export0", "node-name": "drive_image1", "type": "nbd", "writable": true}}
4. In src, add tls creds, add target node and start mirror from src to dst
{"execute":"object-add","arguments":{"qom-type":"tls-creds-x509","id":"tls0","dir":"/etc/pki/qemu","endpoint":"client","verify-peer":true}}
{"execute":"blockdev-add","arguments":{"driver":"nbd","server":{"type":"inet","host":"$ip_dst","port":"3333"},"export":"drive_image1","tls-creds":"tls0","tls-hostname":"dell-per440-08","node-name":"migration-0","read-only":false,"discard":"unmap"}}
{"execute":"blockdev-mirror","arguments":{"job-id":"j0","device":"drive_image1","target":"migration-0","sync":"full"}}
5. After mirror job reach ready status, set migration capabilities in both src and dst.
For src:
{"execute": "migrate-set-parameters", "arguments": {"tls-creds": "tls0"}, "id": "X4NuslWN"}
{"execute":"migrate-set-capabilities","arguments":{"capabilities":[{"capability":"events","state":true},{"capability":"pause-before-switchover","state":true}]}}
For dst:
{"execute":"migrate-set-capabilities","arguments":{"capabilities":[{"capability":"events","state":true},{"capability":"late-block-activate","state":true}]}}
{"execute": "migrate-incoming","arguments": {"uri": "tcp:[::]:5000"}}{"return": {}}{"timestamp": {"seconds": 1713498636, "microseconds": 986768}, "event": "MIGRATION", "data": {"status": "setup"}}
{"execute": "migrate-set-parameters", "arguments": {"tls-creds": "tls0"}, "id": "X4NuslWN"}
6. In src, migrate from src to dst
{"execute": "migrate","arguments":{"uri": "tcp:$ip_dst:5000"}}
7. After migration reach pre-switchover status, cancel mirror jobs
{"execute":"block-job-cancel","arguments":{"device":"j0"}}
8. Continue migration.
{"execute":"migrate-continue","arguments":{"state":"pre-switchover"}}
9. Check vm status in dst
(qemu) info vm
VM status: running
10. Quit vm
(qemu) quit
Expected results
Dst vm can quit successfully.
Actual results
After step10, vm hang with gdb info:
