Have you done 'yum install xen' ? Sorry. I mis-spoke there.

Please open bugs and CC me on them (ketuzsezr@xxxxxxxxxx) CPU features/flags are just outright is not there. I tend to run into the problems as I am trying to use Xen for my development environment. I have posted fixes and bugs in the past and will in the future. But Xen/Centos does not have a big dedicated development or a small one for that matter. So Xen development will lag a bit. This is not a criticism but just a fact of life. > >> Libvirt support for KVM is very good because RH pays people to support KVM. >> Xen under the old config format has reasonable support(possibly 60% of >> features) but under libxl the support is much worse (possibly 30% of >> features). > Please file bugs so we can figure out which ones are missing. When I fight my way through my current provisioning environment I will be likely posting more bugs. I have to admit that I am not the best contributor because often I just fix the bugs. Partly because being outside the community learning all the nuances of posting fixes is way more effort than just fixing them. > >> Thirdly RedHat has been active at times to remove Xen support in favour >> of KVM(Their own virtualization technology). > Not sure I follow as Fedora does not make this distinction. As of the last time I checked you could not build a RedHat 7 kernel with Xen enabled. The point to be made is that Fedora is not RHEL and Centos is more like RHEL. So comparing Centos to Fedora is like complaining that RHEL should support all the current Fedora packages/features. There is a relationship between all of them but they are not the same. > >> Xen has been driven to some extents by the needs of Citrix and although >> they have helped others build packages for Fedora and libvirt its a good >> will effort and its hard to expect Citrix to spend effort on work that >> may not be in their best corporate interests. >> >> >> >> >> On 09/08/2015 09:02 AM, Itamar Reis Peixoto wrote: >>> >>>> not fragment to a bunch of different individual people making a bunch of >>>> different RPM sets that the community does not know who produces, etc. >>>> >>> what you're doing its a complete crap, what you said is different from >>> what you did, why you' (centos virt sig) not contributed to the work >>> of fedora guys instead of reinventing the wheel ? >>> >>> >>> >>> _______________________________________________ >>> CentOS-virt mailing list >>> CentOS-virt@xxxxxxxxxx >>> https://lists.centos.org/mailman/listinfo/centos-virt >> >> -- >> Alvin Starr || voice: (905)513-7688 >> Netvel Inc. || Cell: (416)806-0133 >> alvin@xxxxxxxxxx || >> >> _______________________________________________ >> CentOS-virt mailing list >> CentOS-virt@xxxxxxxxxx >> https://lists.centos.org/mailman/listinfo/centos-virt > _______________________________________________ > CentOS-virt mailing list > CentOS-virt@xxxxxxxxxx > https://lists.centos.org/mailman/listinfo/centos-virt -- Alvin Starr || voice: (905)513-7688 Netvel Inc. || Cell: (416)806-0133 alvin@xxxxxxxxxx || _______________________________________________ CentOS-virt mailing list CentOS-virt@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos-virt
