Except the VirtSIG provides a different version/build of libvirt rpms, so we 
still need to enable RBD/Ceph support separately in VirtSIG provided version..

Works here as a drop-in replacement for the 'regular' qemu-kvm packages 
running Windows 7 as a guest.  I am still looking forward to seeing what 
the '-ev' packages bring to the table over the regular qemu-kvm 
packages, but Win7 seems a bit more responsive under '-ev' than under 
the regular packages.


I actually rebuilt from the latest .src.rpm on cbs rather than using the 
pre-built ones, but am looking forward to following this.


In what repo will the '-ev' packages reside for update purposes?

Re: [CentOS-virt] Xen Doc Day: Guide to setting up bridging on CentOS 6 / 7

2015-10-28 Thread Nathan March 
If you'd like to extend that a little bit, here's example configs on how to do 
LACP and vlan tagging on c6:

host network-scripts # cat ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
USEERCTL=no
BOOTPROTO=none
IPV6INIT=no
MTU=1500
MASTER=bond0
SLAVE=yes

host network-scripts # cat ifcfg-eth1
DEVICE=eth1
ONBOOT=yes
USEERCTL=no
BOOTPROTO=none
IPV6INIT=no
MTU=1500
MASTER=bond0
SLAVE=yes

host network-scripts # cat ifcfg-bond0
DEVICE=bond0
ONBOOT=yes
USEERCTL=no
BOOTPROTO=none
IPV6INIT=no
BONDING_OPTS="miimon=100 mode=802.3ad"

host network-scripts # cat ifcfg-vlan###
DEVICE=vlan###
ONBOOT=yes
USEERCTL=no
BOOTPROTO=none
IPV6INIT=no
PHYSDEV=bond0
VLAN=yes
VLAN_NAME_TYPE=VLAN_PLUS_VID_NO_PAD
IPADDR=10.x.x.x
NETMASK=255.255.255.0
GATEWAY=10.x.x.x
DOMAIN="example.com"
DNS1=x.x.x.x
DNS2=x.x.x.x
DNS3=x.x.x.x

I use my own bridging control scripts, but this should extend your existing doc 
nicely just by using BRIDGE=xenbr0 in the ifcfg-vlan### file.

Also there's a small error in your c6 doc, you specify ifcfg-$dev but $dev 
never gets set anywhere.

Hey Nathan,

Thanks for the feedback.  I meant the HOWTOs to be for a super-basic
setup. I presume someone who wants vlans and what-not can read the
full RHEL 6 / 7 documentation (which I linked to from the parent
document, https://wiki.centos.org/HowTos/Xen/Xen4QuickStart.

If you want to add a new wiki page with your suggested setup, and link
to it from the main page, that would be good as well.

Ah, thanks -- missed that one when copy-and-pasting from my testing scripts. :-)

May I ask what is the difference between the kvm-qemu package from Base 
CentOS 7 repo?


Thanks,
Eliezer

Once we have some testing, we can push and announce via
mirror.centos.org for wider adoption.
