[CentOS-virt] Clocksource boot issues 4.9.13
Hi all I’ve got a few Intel Z87 chipset machines with Adaptec 5405 raid cards (latest firmware), they work fine on 3.18 but during Dom0 boot using kernel 4.9.13 it hangs at “Using clocksource tsc” and the aacraid driver keeps trying to reset Has anyone seen anything like this? I’ve tried specifying clocksource=xen in grub instead of the default of tsc, and that has the same issue. HPET is enabled and Xen is seeing it: (XEN) ACPI: HPET D9649CB0, 0038 (r1 ALASKAA M I 1072009 AMI.5) (XEN) Platform timer is 14.318MHz HPET Thanks Chris ___ CentOS-virt mailing list CentOS-virt@centos.org https://lists.centos.org/mailman/listinfo/centos-virt
Re: [CentOS-virt] Xen Security patching
When are the kernel and xen RPM’s going to be updated again? I can’t see anything in the RC tree since April and there are a fair number of XSA’s + kernel patches in 3.10 since.

In other news I’ve been doing some testing of the 3.10 kernel and so far so good! That is not true ... I updated testing RPMS into the rc1 tree and announced it here: http://lists.centos.org/pipermail/centos-virt/2013-November/003485.html If I can get at least one or 2 people to tell me this works, I'll push it. Thanks, Johnny Hughes By not true, I mean that all XSAs that are applicable up to xsa-72 are in the xen-4.2.3-24 RPMS in the RC1 repo right now. I have gotten 0 feedback since I released them. (xsa-62 through xsa-72) xsa-73, xsa-75, xsa-78 can be released now, but they are very new. OK, a newer version of xen-4.2.3-25 now exists in xen-RC-1 ... this includes xsa-73, xsa-75, and xsa-78 Please test and provide feedback so we can move these to production. I have just updated my production xen dom0 machines to this version, and I am not seeing any issues. I don't necessarily recommend that for everyone, but can we get some feedback from xen4centos6 users so we can move these to production. The repo is at for those who need the info: http://dev.centos.org/centos/6/xen-c6-RC1/ Thanks, Johnny Hughes signature.asc___ CentOS-virt mailing list CentOS-virt@centos.orgmailto:CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt
[CentOS-virt] xen_balloon: reserve_additional_memory: add_memory() Errors
Hi All Back in August there was a report of these errors popping up in dmesg, and as far as I can tell it's still unresolved even in the latest kernel. System RAM resource [mem 0xc800-0xcfff] cannot be added xen_balloon: reserve_additional_memory: add_memory() failed: -17 On this example its running 3.10.20-11.el6.centos.alt.x86_64 To replicate this just disable Dom0 memory ballooning in /etc/xen/xend-config.sxp and these errors will over time completely fill up dmesg. This is because the amount of memory within these two sys files is different: /sys/devices/system/xen_memory/xen_memory0/info/current_kb /sys/devices/system/xen_memory/xen_memory0/target_kb We can manually edit to work around the problem and stop the error but its not ideal, I would help with making a patch but don't really know where to start!

[CentOS-virt] Xen Security patching
Hi Guys When is the next update of Hypervisor packages going to be released? There appears to be no changes to the main hypervisor RPMs since September (Even in the BETA / RC1 tree) and there are 5+ Xen Security Advisories with patches which need to be added. Security issues are handled and released in sync with public disclosure upstream with zero lag I can rebuild my own, but that's not really the point. In other news I've been doing some testing of the 3.10 kernel and so far so good!
