So far there's been no issues, but it's only been since Friday. Also, I found this: https://xen.crc.id.au/support/guides/install/ There's a 4.4 kernel here built for Xen Dom0, which I'm giving a whirl to see how stable it is, also only since Friday. I'm not using anything else he's packaged from his repo. On a related note, does the SIG have plans to replace the 3.18 kernel which is marked as projected EOL of January 2017 (https://www.kernel.org/category/releases.html)? -- Kevin Stange Chief Technology Officer Steadfast | Managed Infrastructure, Datacenter and Cloud Services 800 S Wells, Suite 190 | Chicago, IL 60607 312.602.2689 X203 | Fax: 312.602.2688 kevin at steadfast.net | www.steadfast.net
