networkinterface type proposal
Hi - I''ve searched around and haven''t found anyone who''s implemented a type+provider for configuring network interfaces in puppet. Does anyone have such a thing already running that''s just not on forge / github? I found some prior art (aside from the old ''interface'' type which was deleted in 0.24) but most people seem to use definitions +

How to kickstart a guest with Centos 6.6 & Xen 4.4
Hello,
I posted a question over at xenproject.org but it was recommended that I
send out a message here for help.
My post there:
http://www.xenproject.org/help/questions-and-answers/vanilla-pv-centos-guest-via-kickstart-centos-6-6,-xen-4-4.html
The TL;DR is: Everything I've found to kickstart a new vanilla rhel/centos
guest points to specifying a kernel & and initrd- for RHEL/Centos 5.

Xen hypervisor on CentOS 7.4 with modern UEFI server not booting from grub
Hi,
I installed CentOS 7.4 on a modern Lenovo ThinkSystem SR630 server
which uses UEFI. So far so good CentOS 7.4 works fine so then I went
on to install the Xen hypervisor by following the instructions from
the wiki (https://wiki.centos.org/HowTos/Xen/Xen4QuickStart).
Unfortunately when I reboot after having installed the xen package the
system does not boot into "CentOS Linux, with Xen

Open graphics connection with virt-manager problem
Hi,
Actually, we study virtualization on CentOS with Xen, our goal is to test if the migration of Xen with SLES 11 to CentsOS.
Our first tests are ok except for one problem and I don't find any solutions on the net. I hope, you can help me.
The problem is that I can't connect to my vm desktop with Virt-Viewer. I follow the installation guide available for centos?:

libvirt, xen PV, qemu-system-i386, root user
Hi, after migrating to libvirt/libxl according to:
https://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt
I've noticed that my Xen PV domains are being launched by
qemu-system-i386 running under root privileges.
I am wondering why is this? Previously no qemu process was used.
If qemu is needed for some reason, are there any guidelines for non-root
operation?
Thanks

Is Xen on CentOS 7 production ready?
I see the announcement from February that it's available, but is it
considered to be safe for Production use? The documentation in the SIG
still only references CentOS 6.

True bond howto for Centos 6
Hi all,
Read many posts on the subject.
Using 802.3ad.
Few problems;
Cannot ping some hosts on the network, they are all up.
Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts.
Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway.
When cold booting it somewhat works, some hosts are pingable while

Can't create new Xen domains using libvirt on CentOS 6.5
Hello,
we have a strange problem on a fresh install of CentOS 6.5. On the
server we want to use Xen to host paravirtualised guests (the system has
no hardware virtualization support). To manage the domain we would like
to use libvirt. Xen and libvirt are set up as described here:

Using network-script with Xen 4.4.1 (aka what will I do without xend?)
I normally use the network-script parameter in the
'/etc/xen/xend-config.sxp' configuration file to configure network
bridges. However, the latest release of Xen4CentOS (which comes with Xen
4.4.1) has xend disabled by default.
Can I continue to use network-script without xend? If not what is the
recommended method for automatically configuring network bridges with the
latest release of

anaconda/kickstart: bonding device not created as expected
Hi,
I am currently struggling with the right way to configure a bonding
device via kickstart (via PXE).
I am installing servers which have "eno" network interfaces. Instead of
the expected bonding device with two active slaves (bonding mode is
balance-alb), I get a bonding device with only one active slave and an
independent, non-bonded network device. Also the bonding device
