RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description CongDong 2014-06-27 06:02:58 UTC 
Description of problem:
When use domxml-to-native to convert a spice guest xml which no spice tls port,
it requires to enable spice tls option in qemu.conf

Version-Release number of selected component (if applicable):
libvirt-1.1.1-29.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Prepare a spice guest xml without spice tls port like this:
# cat vm.xml
...
    <graphics type='spice' port='5900' autoport='yes' listen='127.0.0.1'>
      <listen type='address' address='127.0.0.1'/>
    </graphics>
...
2. # virsh domxml-to-native qemu-argv vm.xml

Actual results:
Get error:
error: unsupported configuration: spice TLS port set in XML configuration, but TLS is disabled in qemu.conf

Expected results:
domxml-to-native should convert the xml to native guest configuration format

    qemu: fix domxml-to-native failing when spice_tls is not enabled
    
    The default graphics channel mode is 'any', so as to defaultMode attribute.
    If defaultMode and channel mode are all the default value 'any',
    qemuConnectDomainXMLToNative will set TLSPort.
    But in qemuBuildGraphicsSPICECommandLine, if spice_tls is not enabled, libvirtd
    will report an error to tell the user that spice TLS is disabled in qemu.conf.
    
    So qemuConnectDomainXMLToNative should check spice_tls is enabled,
    then decide to allocate an tlsPort number to this graphics.
    
    If user specified defaultMode is 'secure', qemuConnectDomainXMLToNative
    could allocate tlsPort, and then let qemuBuildGraphicsSPICECommandLine reports
    the spice_tls disabled error.

Comment 4 vivian zhang 2014-11-27 09:55:46 UTC 
I can produce this bug on build 
libvirt-1.1.1-29.el7.x86_64

verify it on build
libvirt-1.2.8-9.el7.x86_64
qemu-kvm-rhev-2.1.2-12.el7.x86_64

verify steps:

1. prepare a guest xml with below content:
...
<graphics type='spice' port='5900' autoport='yes' listen='127.0.0.1'>
      <listen type='address' address='127.0.0.1'/>
    </graphics>
...

3. modify xml to defaultMode = secure
....
<graphics type='spice' port='5900' autoport='yes' listen='127.0.0.1' defaultMode='secure'>
      <listen type='address' address='127.0.0.1'/>
<channel name='main' mode='insecure'/>
      <channel name='display' mode='insecure'/>
    </graphics>
....

4. # virsh domxml-to-native qemu-argv /tmp/rhel7new.xml 
error: unsupported configuration: spice TLS port set in XML configuration, but TLS is disabled in qemu.conf

5. change spice_tls =1 in qemu.conf and restart libvirtd 
spice_tls = 1
