Installing support for q35 chipset
by admin＠siegel-tech.net 25 Jun '18

25 Jun '18

Hello I have recently had to reinstall Centos 7.5 to on host computer. I have not be able to set-up qemu to support the q35 chip set. I have several virtual machines that require q35. This is not my first install, I have configured libvirt on many machines in the past, it just worked, it has not required any manual configuration. [root@sj aadmin]# /usr/libexec/qemu-kvm -machine help Supported machines are: none empty machine pc RHEL 7.0.0 PC (i440FX + PIIX, 1996) (alias of pc-i440fx-rhel7.0.0) pc-i440fx-rhel7.0.0 RHEL 7.0.0 PC (i440FX + PIIX, 1996) (default) rhel6.6.0 RHEL 6.6.0 PC rhel6.5.0 RHEL 6.5.0 PC rhel6.4.0 RHEL 6.4.0 PC rhel6.3.0 RHEL 6.3.0 PC rhel6.2.0 RHEL 6.2.0 PC rhel6.1.0 RHEL 6.1.0 PC rhel6.0.0 RHEL 6.0.0 PC I have add the jenkins repository. and installed the following packages, OVMF.noarch 20171011-4.git92d07e48907f.el7 @base edk2.git.x86_64 0-20180612.181.g2aedaaef8a @qemu-firmware-jenkins edk2.git-aarch64.noarch 0-20180612.181.g2aedaaef8a @qemu-firmware-jenkins edk2.git-arm.noarch 0-20180612.181.g2aedaaef8a @qemu-firmware-jenkins edk2.git-ovmf-x64.noarch 0-20180612.181.g2aedaaef8a @qemu-firmware-jenkins edk2.git-tools.x86_64 0-20180612.181.g2aedaaef8a @qemu-firmware-jenkins coreboot.git.x86_64 4.8-599.333.g1bf411c743 @qemu-firmware-jenkins coreboot.git-tools.x86_64 4.8-599.333.g1bf411c743 @qemu-firmware-jenkins qemu-common.x86_64 2:2.0.0-1.el7.6 @epel qemu-guest-agent.x86_64 10:2.8.0-2.el7 @anaconda qemu-img.x86_64 10:1.5.3-156.el7_5.2 @updates qemu-kvm.x86_64 10:1.5.3-156.el7_5.2 @updates qemu-kvm-common.x86_64 10:1.5.3-156.el7_5.2 @updates qemu-kvm-tools.x86_64 10:1.5.3-156.el7_5.2 @updates qemu-system-alpha.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-arm.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-cris.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-lm32.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-m68k.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-microblaze.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-mips.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-moxie.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-or32.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-s390x.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-sh4.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-unicore32.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-x86.x86_64 2:2.0.0-1.el7.6 @epel qemu-system-xtensa.x86_64 2:2.0.0-1.el7.6 @epel qemu-user.x86_64 2:2.0.0-1.el7.6 @epel seabios.git.x86_64 1.11.0-40.27.gd9a8b86 @qemu-firmware-jenkins I have installed the Virtualization Host group.

Re: [CentOS-virt] Q: how can I request to add an upstream patch to resolve a core dump issue?

UPDATE: It turned out QEMU still dumped core with that patch applied. That said, I'm still interested to know how to report issues with QEMU from centos-virt repo.

Q: how can I request to add an upstream patch to resolve a core dump issue?
by Xiong, Huan 22 Jun '18

Hi, The latest version of QEMU (qemu-kvm-ev-2.10.0-21.el7_5.3.1) from centos-virt repo doesn't have this patch: commit 68a9398261ca38979bbc2b7c89ed5bb044ccc9e6 Author: linzhecheng <linzhecheng(a)huawei.com> Date: Tue Nov 28 12:46:56 2017 +0800 qemu-thread: fix races on threads that exit very quickly I wonder how I can request to add it? I hit a core dump issue repeatedly, which I believe is fixed by this patch. While I observed it on an aarch64 machine, I think the issue is common on all arch types. I'd like to submit a bug report, but didn't find a category for centos-virt at https://Bugzilla.redhat.com (I suppose I should file bug against upstream, right?). The Virt-SIG wiki page seems to be outdated and doesn't contain information on this. Any suggestions? Thanks, Ray
