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.

Fixed In Version: virt-viewer-0.5.2-6.el6
Doc Type: Bug Fix
Doc Text:
Cause: The URI parsing code did not expect URIs containing '[', ']' around the host component Consquence: It was not possible to connect to remote libvirt servers whose URI address contained raw IPv6 addresses (eg qemu+ssh://root@[2001::xxxx:1]/system ). Fix: The URI parsing was fixed to take account of the IPv6 address syntax Result: It is now possible to connect to remote libvirtd servers using raw IPv6 addresses

Red Hat Product Errata RHBA-2012:0772 0 normal SHIPPED_LIVE virt-viewer bug fix and enhancement update 2012-06-19 20:35:11 UTC

Description David Jaša 2012-04-17 15:29:54 UTC 
Description of problem:
support ipv6 addresses on CLI. IPv6 passed via controller works.

Version-Release number of selected component (if applicable):
virt-viewer-0.5.2-4

How reproducible:
always

Steps to Reproduce:
try to connect to qemu over ipv6:
1. remote-viewer spice://ipv6_addr/?port=PORT
2. remote-viewer spice://[ipv6_addr]/?port=PORT
3.
  
Actual results:
none of above works

Expected results:
some of above works

Additional info:
when address is passed via controller, remote-viewer works
Comment 1 Daniel Berrangé 2012-04-18 15:45:35 UTC 
The RFC compliant syntax would be the second example you give

>  remote-viewer spice://[ipv6_addr]/?port=PORT

I have confirmed that this is indeed broken for both SPICE and VNC. The VNC support can be fixed in virt-viewer itself. The SPICE fix needs to be done in SPICE-GTK
Comment 2 Daniel Berrangé 2012-04-18 15:47:38 UTC

Comment 3 Daniel Berrangé 2012-04-23 17:05:14 UTC 
Fixes for libvirt URIs and VNC URIs in virt-viewer-0.5.2-6.el6

Fix for SPICE URIs is to be handled by bug 813865 against spice-gtk

2:make sure ipv6 worked for libvirt

can't connect to guest,the bug not fixed.
Comment 6 Daniel Berrangé 2012-04-24 08:14:31 UTC 
> <graphics type='vnc' port='5901' autoport='yes' listen='0.0.0.0'>

You have told the guest to listen on a IPv4 address, so of course you can't connect to it using IPv6.
Comment 7 zhe peng 2012-04-24 08:52:38 UTC 
thanks daniel,
I change listener to 
 <graphics type='vnc' port='5902' autoport='yes' listen='::'>
      <listen type='address' address='::'/>
    </graphics>
remote-viewer can connect the guest
vnc verification passed.
waiting for spice-gtk latest build to try spice guest connection.
Comment 8 zhe peng 2012-05-23 07:25:13 UTC 
vnc support ipv6 now, spice-gtk not support this on rhel6.3,bug 813865 will fix on
rhel6.4, so move this bug to verified, when 813865 fixed,will add comments on this.
