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 (i440F...

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. Newer versions of libvirt and QEMU will probably switch over to defaulting to Q35 in the near future. None of this matters...

...e target hypervisor. For example in the Glance case we have to write something which will be picked up by Nova much later: > > + "hw_machine_type", > > + (match guestcaps.gcaps_machine with > > + | I440FX -> "pc" > > + | Q35 -> "q35" > > + | Virt -> "virt"); I read the Nova code and it seems very ad-hoc. As far as I can tell these strings are eventually passed down to libvirt. However libvirt capabilities doesn't advertise these machine types exactly, but something more li...

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 the default machine type but to specify what we ne...

Hello. I'm not able to disable the sata controller on a machine='pc-q35-2.1' type VM. Whenever i delete: <controller type='sata' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x1f' function='0x2'/> </controller> it gets added again when i close the editor....

I built 2.3.0-rc0 but also added RH patches which applied (mainly for pc-q35-rhel7.1.0 machine type support) from http://ftp.redhat.com/pub/redhat/linux/enterprise/7Server/en/RHEV/SRPMS/qemu-kvm-rhev-2.1.2-23.el7_1.1.src.rpm After suspending and restoring VM prints the following and hangs: [root localhost ~]# [ 43.595571 irq 23: nobody cared (try booting with the "ir...

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 at sj aadmin]# /usr/libexec/qemu-kvm -machine help Supported machines are: none...
