CentOS 3 Comments

hi guys,

I updated to qemu–kvm-common-ev-2.12.0-18.el7_6.1.1.x86_64 (also libvirt) and my CentOS 6.10 kvm guests now do not start.

Funnily enough Win10 guest are fine, only CentOSes cannot start, silently & without any errors.

Any care to comment?

many thanks, L.

  • It looks like you installed CentOS 7 packages on a CentOS 6 system. I’m amazed it even worked. Try removing the packages and re-installing the appropriate packages for CentOS 6.

  • Oh, never mind me, I missed that you were saying that your *GUESTS*
    don’t start.

    Did you do a full update to CentOS 7.6.1810, or just the libvirt/qemu packages?

  • CentOS 7 (qemu package version).

    So, host is CentOS 7 updated to the latest (no fasttrack repo, but cr(rolling) yes) and quests are(if not gone now?)  CentOS 6.10.

    virsh start such a guest okey, complains of nothing, no errors but guess does not boot. I see qemu BIOS and boot menu but when it comes to booting the OS/grub/kernel, then this does not happen.

    Checking qcow image with qemu confirms images are free of errors, etc. I
    can mount these CentOS guests okey, filesystem seems good.

    I do not want to downgrade just yet, but will have to check that option soon.
