[ovirt-users] Spice Client Connection Issues Using aSpice

Wed Feb 21 01:05:57 UTC 2018

Hello everyone,

I can confirm that spice is working for me when I launch it using the .vv file.  I have virt viewer installed on my Windows pc and it works without issue.  I can also launch spice when I use movirt without any issues.  I examined the contents of the .vv file to see what the certificate looks like.   I can confirm that the certficate in the .vv file is the same as the file I downloaded in step 1 of my directions.

I reviewed the PKI reference (https://www.ovirt.org/develop/release-management/features/infra/pki/)  <https://www.ovirt.org/develop/release-management/features/infra/pki/>

for a second time and I see the same certificate located in different locations.

For example, all these locations contain the same certificate-

  *   <https://ovirtengine.lan/ovirt-en> https://ovirtengine.lan/ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA
  *   /etc/pki/vdsm/certs/cacert.pem
  *   /etc/pki/vdsm/libvirt-spice/ca-cert.pem
  *   /etc/pki/CA/cacert.pem

This is the certificate I am using to configure my aSpice client.

Can someone answer the question from my original post?  The PKI reference says for version 3.2 and 3.3.  Is the documentation still correct for version 4.2?

At this point I am trying to find out where the problems exists - ie.

#1 Is my client not configured correctly?

#2 Am I using the wrong cert?  (I think I am using the correct cert based on the research I listed above)

#3 Does my client need to be able to send a pasword?  (based on the contents of the .vv file, I'd have to guess yes)

Also my xml file for the VM in question contains this:

 <graphics type='spice' autoport='yes' defaultMode='secure' passwd='*****' passwdValidTo='1970-01-01T00:00:01'>
Please note:  I did not perform any hand configuration of the xml file, it was all done by the system using the UI.
#4 Can I configure a file on the system to turn off ticketing and passwords and see if that makes a difference, if so, what file?

#5  Can someone explain this error?

140400191081600:error:14094438:SSL routines:ssl3_read_bytes:tlsv1 alert internal error:s3_pkt.c:1493:SSL alert number 80
((null):27595): Spice-Warning **:reds_stream.c:379:reds_stream_ssl_accept: SSL_accept failed, error=1

What I know about it is this:
According to RFC 2246, the alert number 80 represents an "internal error".  Here is the description from the RFC
internal_error: An internal error unrelated to the peer or the correctness of the protocol makes it impossible to continue (such as a memory allocation failure). This message is always fatal.

#6 Could this error be related to any of #1 through #4 above?

Thanks!

Feels to me like OP should try to get it working _any_ "normal" way
before trying to get the special use case application working?

Like trying to run before learning to crawl, if that makes sense?

I would suggest just logging in to webadmin with a regular PC and
trying to get a SPICE console with remote-viewer to begin with. Then,
once that works, try to get a SPICE console working through moVirt with
aSPICE on an Android phone, or one of the Chromebooks you have to play
with before going into production. Once that´s settled and you know it
should work the way you normally access it, you can start playing with
your special use case application.

Hope it helps!
