Thanks George.
As there are now quite many options to choose from, what would be the best option performance wise for running 32bit domUs under xen-4.6?
Best, Peter

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:

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.
