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

Description

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
Upstream virt-viewer patch for VNC side of things: https://www.redhat.com/archives/virt-tools-list/2012-April/msg00094.html 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
Technical note added. If any revisions are required, please edit the "Technical Notes" field
accordingly. All revisions will be proofread by the Engineering Content Services team.

test pkgs:
virt-viewer-0.5.2-6.el6.x86_64
libvirt-0.9.10-13.el6.x86_64
step:
1:configure ipv6 global addr
#ifconfig eth0 inet6 add 3ffe::102/64
2:make sure ipv6 worked for libvirt
#virsh -c qemu+ssh://[3ffe::102]/system
root@3ffe::102's password:

3:prepare a guest with vnc
.......
<graphics type='vnc' port='5901' autoport='yes' listen='0.0.0.0'>
<listen type='address' address='0.0.0.0'/>

.......
4:use remote-viewer to connect the guest

can't connect to guest,the bug not fixed.
> <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.
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.
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.
