update : working with embedded ca. (one line, with \n to separate lines of the ca file)

It's working for me with: 


server 
------- 
push @$cmd, '-spice',"tls-port=60100,disable-ticketing,$x509,tls-ciphers=DES-CBC3-SHA"; 


client 
------ 
#remote-viewer testtls.conf 



cp pve-root-ca.pem /home/spirit/.spicec/spice_truststore.pem 


test.conf file: 

[virt-viewer] 
type=spice 
host=kvmtest1.odiso.net 
tls-ciphers=DES-CBC3-SHA 
tls-port=60100 




about ca.pem, it should be possible to add it in configuration file 

https://git.fedorahosted.org/cgit/virt-viewer.git/tree/src/virt-viewer-file.c 
* - ca: string PEM data (use \n to seperate the lines)

Hi, Dietmar, sorry I was busy this morning. 

To get it work, I need to force cipher on server. 

this works for me: 

push @$cmd, '-spice',"port=xxx,tls-port=xxx,disable-ticketing,$x509,tls-ciphers=DES-CBC3-SHA"; 


(I think that port= is optionnal, should work with tls-port only) 

you can also try to force all channels with tls 

",tls-channel=main,tls-channel=display,tls-channel=inputs,tls-channel=cursor,tls-channel=playback,tls-channel=record,tls-channel=usbredir" 


I'll redo test today to send you a full working patch.

And if I try to connect to the other port 

# remote-viewer spice://localhost:3001 

then kvm print this error: 

139895458642144:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number:s3_pkt.c:348:
