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 you...

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.

I'd forgotten about that despite being the one who ran into it. Looks like that patch was just removed in 4.9.75-30 which I just upgraded this system to:

Looks like I can reproduce this pretty easily, this happened upon ssh'ing into the server while I had a VM migrating into it. The system goes completely unresponsive (can't even

Thanks for the heads-up. It's been running through XenServer's tests as well as the XenProject's "osstest" -- I haven't heard of any additional issues, but I'll ask. It's possible also that it's some interaction between the...

This has been an issue for me for over 1 year. I have tried several boards but I do not get responses anywhere. Please take a look at this post. Towards the end i pastebined a wine.log with detailed debug output. Any help would be greatly appreciated. http://forum.winehq.org/viewtopic.php?t=6143 Bobby -------------- next part -------------- An HTML attachment was scrubbed... URL:
