Just a heads up that I'm seeing major stability problems on these builds. Didn't have console capture setup unfortunately, but have seen my test hypervisor hard lock twice over the weekend.
This is with xpti being used, rather than the shim.
Cheers, Nathan

packages
making their way to centos-virt-xen-testing
I've built & tagged packages for CentOS 6 and 7 4.6.6-9, with XPTI "stage 1" Meltdown mitigation.
This will allow 64-bit PV guests to run safely (with a few caveats), but incurs a fairly significant slowdown for 64-bit PV guests on Intel boxes (including domain 0).
If you prefer using Vixen / Comet, you can turn it off by adding 'xpti=0' to your Xen command-line.
Detailed information can be found in the XSA-254 advisory:
https://xenbits.xen.org/xsa/advisory-254.html
Please test and report any issues you have. I'll probably tag then with -release tomorrow.
4.8 packages should be coming to buildlogs soon.
