[pve-devel] spice tls + proxy: ssl_verify.c:484:openssl_verify: ssl: hostname

[Alexandre DERUMIER]

I think I got how it's works.


when we send client_migrate_info qmp, client is connecting to the standby target guest. (reconnect through the original http proxy)
At the end of the migration, the client switch to the new host.

the seamless-migration=on flag, help the client to do a transparent migration (copy mouse position, memory video state,etc...)


One problem:

the client_migrate_info  host= value (proxyticket), seem to crash the client if the value is > 247 characters.
Do you think it's possible to reduce the proxyticket size ?

about seamless migration, they are 2 mode: 

true seamless migration, adding seamless-migration=on to spice server options. 

semi-semless migration (client disconnect/reconnect to spice). 

But documentation is not very clear, I don't known if I need to use client_migrate_info with true seamless mode. 

Also, in my firsts tests, spice client disconnect when receive client_migrate_info....(it should wait for the end of the migration). 

I'll continue tests, I'll send a report tomorrow.

Works fine on my test cluster ! Thanks ! 


I'll try to see how seamless migration works. 
I known we can send new host,port values with qmp , but I don't known how it's works with proxy and proxyticket (as we have a timestamp). 


" 
client_migrate_info 
------------------ 

Set the spice/vnc connection info for the migration target. The spice/vnc 
server will ask the spice/vnc client to automatically reconnect using the 
new parameters (if specified) once the vm migration finished successfully. 

Arguments: 

- "protocol": protocol: "spice" or "vnc" (json-string) 
- "hostname": migration target hostname (json-string) 
- "port": spice/vnc tcp port for plaintext channels (json-int, optional) 
- "tls-port": spice tcp port for tls-secured channels (json-int, optional) 
- "cert-subject": server certificate subject (json-string, optional)

Just implemented that - please can you test?
