similar to: "Vixen" HVM shim package available in 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.

Hi, I am very sorry to do this on short notice, but obviously Meltdown and Spectre are a lot more than anyone was really expecting to come down the pipeline. Xen 4.4 has been EOL upstream for about a year now and I have personally been reviewing and backporting patches based on the 4.5 versions made available upstream. Given that 4.5 is now also reaching EOL, backporting to 4.4 will become

http://computerchristmas.com/ForumBoard/read.php?f=2&i=198&t=193 said Vixen worked with Wine, so I tried it, and sure enough, it seems to run. It's kind of cool to see .real net apps working with Wine. Here's how I tested: $ rm -rf .wine $ wget http://www.vixenlights.com/releases/Vixen%202.0%20Release.zip $ wget http://kegel.com/wine/winetricks $ sh ~/winetricks corefonts

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 > -----Original Message----- > From: CentOS-virt [mailto:centos-virt-bounces at centos.org] On Behalf Of > George Dunlap

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?

Dear Security Team, I have prepared a new upload addressing a number of open security issues in Xen. Due to the complexity of the patches that address XSA-273 [0] the packages have been built from upstream's staging-4.8 / staging-4.10 branch again as recommended in that advisory. Commits on those branches are restricted to those that address the following XSAs (cf. [1]): - XSA-273

I've got a first cut of the rebase here: git://github.com/gwd/sig-virt-xen out/update-4.4.1-rc1-ee81dda-RFC To build it, you'll need to download the polarssl tarball: http://xenbits.xen.org/xen-extfiles/polarssl-1.1.4-gpl.tgz And you'll need a tarball based on (unfortunately) a private tree, which you can find here: git://github.com/gwd/xen base/update-4.4.1-rc1-ee81dda-RFC This

Hello, Are XSA-289 and XSA-274/CVE-2018-14678 fixed with Xen recent 4.8, 4.10 and kernel 4.9.177 packages ? Thank you

Xen 4.4.4 along with kernel 4.9.44 containing patches for XSAs (226 - 230) from August 15th are now available in centos-virt-testing. If possible, please test and provide feedback here so we can move these to release soon. XSA-228 did not affect Xen 4.4 XSA-229 only applies to the kernel XSA-235 disclosed today only affects ARM and isn't going to be added to these packages. Thanks. --

Kevin has been rolling back the security updates to the 4.4 branch. He has been working with some of the other distros (debian for sure, and some others on the xen security list). I think it is his intention to continue this for as long as he is able to. (Kevin, chime in if you have a schedule lifetime or EOL in mind) As long as Kevin (or anyone else) maintains the tree, I am happy to build
