[Kernel-packages] [Bug 1581681] Re: KVM slowed down with aparently no reason.
Ok so it looks like upgrading to 15.10 the problem has been solved. The "CPU Bug" (attached) is still getting at boot time, but it looks harmless. Also SuperMicro has a FAQ that contains exactly this problem and they say that a BIOS Update solves the problem: http://www.supermicro.com/support/faqs/faq.cfm?faq=20349 But the main problem that is the slow-down of the KVM and the errors on dmesg disappeared when upgrading from 15.04 to 15.10 (that upgrades the kernel from 3.16 to 4.2) - I think this ticket can be closed since the solution is to upgrade the distro (probably better to 16.04) ** Attachment added: "cpu-bug.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1581681/+attachment/4663974/+files/cpu-bug.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1581681 Title: KVM slowed down with aparently no reason.

[Kernel-packages] [Bug 1581681] Re: KVM slowed down with aparently no reason.
Ok, I upgraded to the next release ubuntu asked me (15.10 in this case). Now it is with 4.2.0-36 kernel. The server is running for a few hours without any problem so far. I will test for a few more days and comment again the results here. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1581681 Title: KVM slowed down with aparently no reason.
