CentOS 7 Xen 4.4.3 packages available for in virt7-xen-44-testing
by George Dunlap 27 Sep '15

27 Sep '15

Updated Xen 4.4.3 packages have passed my local smoke tests, and are now available. Full C7 release is still waiting on suitable testing for the libvirt packages. If someone wants to step up to give the libvirt packages a decent smoke test, that will speed the C7 release process significantly. Otherwise it will have to wait until I get a chance to write some automated smoke tests. In the mean time, here's how to install the core Xen packages: rpm -ivh http://cbs.centos.org/repos/virt7-xen-44-testing/x86_64/os/Packages/centos-… This will set up yum repositories for both the eventual release repositories (enabled by default), and the community build system repositories (disabled by default). At the moment, all packages will be stored in the virt-xen-44-testing repository. You can either enable this by default by editing /etc/yum.repos.d/VirtSIG-Xen.repo, or by adding "--enablerepo=virt-xen-44-testing". If you want, you can edit defaults /etc/sysconfig/xen-kernel Next, run 'yum update' to get the new kernel: yum --enablerepo=virt-xen-44-testing update kernel Now install xen: yum --enablerepo=virt-xen-44-testing install xen This should grab both xen and the updated kernel package. It should also automatically: * Add default commandline parameters for Xen and Linux when booting under Xen * Arrange for xen to come up first in the grub * Set the default boot entry to Xen. That's it! Reboot and you should be good to go. Please report any problems or feedback to this list. -George

Try the aforementioned unnumbered option first. Can't say anything about IPv6 - sadly not proficient. For IPv4 you won't need iptables, only iproute: 1)save and delete the current wireless default gateway IP 2)create a source-based policy routing rule so traffic from the fw VM IP address would have the earlier saved IP as a gateway IP 3)set the default gateway IP to the another interface's (it's a requirement) IP address of a fw VM.

OT: adding a wifi adapter to openvswitch
by C.L. Martinez 24 Sep '15

24 Sep '15

Hi all, Finally, I have installed openvswitch from source to two CentOS hosts: one 6.x and other 7.x. I will do some tests using openvswitch bridges to my KVM machines. One of these tests is to add a wlan0 adapter from comandline but only when this wlan0 is associated with a ssid without assign an IP. Is this posible? Do I nees to add some ebtables like, for example, Debian's wiki says here: https://wiki.debian.org/BridgeNetworkConnections#Bridging_with_a_wireless_N… Thanks

Hi Johnny. It’s nice to know Centos 6 is production ready now. I might give it a spin on another OS partition, and see what results I get on a test server. Kind Regards, Keith
