similar to: kvm machine type pc-i440fx-2.1

Hi all, What are the differences between pc and q35?? By default, virt-manager+libvirt setups kvm guest machine as a pc-i440fx-rhel7.1.0. [hicheck at ckvm015 ~]$ /usr/libexec/qemu-kvm -machine ? Supported machines are: pc RHEL 7.1.0 PC (i440FX + PIIX, 1996) (alias of pc-i440fx-rhel7.1.0) pc-i440fx-rhel7.1.0 RHEL 7.1.0 PC (i440FX + PIIX, 1996) (default) pc-i440fx-rhel7.0.0

If you have hardware raid on this machine, try to mount xfs partitions with nobarrier. We had similar freezes and this helped for us.

Hi there, I met one problem that guest fail to boot up when Selinux is enabled with guest storage based on ceph. However, I can boot the guest with qemu directly. I also can boot it up with Selinux disabled. Not sure it is a libvirt bug or wrong use case. 1. Enable Selinux # getenforce && iptables -L Enforcing Chain INPUT (policy ACCEPT) target prot opt source destination

QEMU for x86 supports two machine types, "pc" (emulating the ancient Intel i440FX chipset originally used by the Pentium Pro), and "q35" (https://wiki.qemu.org/Features/Q35). Currently virt-v2v does not set any machine type, so libvirt or the target hypervisor will choose some default, probably i440fx. The latest advice from the QEMU and libvirt communities is not to rely on

Hello. I'd like to determine if it's possible to change the 'machine type' attribute while a vm is running. For example, I have: <os> <type arch='x86_64' machine='pc-i440fx-trusty'>hvm</type> <boot dev='hd'/> </os> I'd like to change that to "machine='pc-i440fx-1.7'" due to an error[1]

Other than adding a new element in the OVF, this also enables the conversion of UEFI guests to oVirt. It is tested? Does it require other changes? I'd split the addition of <BiosType> to the

What's the status of the SATA controller migration bug? Are the patches for it expected to be in 2.4? Looks like they didn't make it into 2.3. Since you last wrote, if the SATA controller patches aren't in yet, is there any new way to avoid the SATA controller device, if you have no SATA devices? Thank you. === REPLYING TO === On 02/23/2015 02:26 PM, Thomas Stein wrote: >

Context: The baremetal host previously had QEMU 2.11. But I manually downgraded the QEMU version (via `dnf downgrade qemu-system-x86`); now it is at 2.10: $ rpm -q qemu-system-x86 qemu-system-x86-2.10.2-1.fc27.x86_64 The guest is offline. Let's see (in a couple of ways) what machine type it has while it is dormant: # virsh dumpxml cirros | grep -i machine= <type
