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.

Comment 3 Jiri Denemark 2012-02-09 10:33:56 UTC 
BTW, there is an ancient bug 624626 reported against libxml2, which requests proper escaping of IPv6 address with '[' and ']' and removing those when parsing URIs. Having that fixed could save us from providing a wrapper for xmlParseURI.
Comment 4 Dave Allan 2012-02-10 21:07:37 UTC 
Don't we have to deal with systems with the broken libxml2 anyway?

Verify it with libvirt-0.9.10-3.el6 and it passed.

The steps are as follows:
Prepare two machine: one client and one server
1. 
1.1 on client host
configure ipv6 global addr:
#ifconfig eth0 inet6 add 3ffe::101
1.2 on server host
configure ipv6 global addr
#ifconfig eth0 inet6 add 3ffe::102

2. 
on client host, execute remote access and issue the bellow command:
# virsh -c qemu+ssh://root@[3ffe::102]/system
root@3ffe::102's password: 
Welcome to virsh, the virtualization interactive terminal.

Type:  'help' for help with commands
       'quit' to quit
