kvm_intel
In CentOS 7.2.1511:
kernel-3.10.0-327.36.3.el7.x86_64
qemu-kvm-1.5.3-105.el7_2.7.x86_64
libvirt-daemon-kvm-1.2.17-13.el7_2.5.x86_64
After upgrade from 7.2.1511 to 7.3.1611:
It was (after upgrading to this version, I noticed described in the first
report the situation):
kernel-3.10.0-514.2.2.el7.x86_64
qemu-kvm-1.5.3-126.el7.x86_64
libvirt-daemon-kvm-2.0.0-10.el7_3.2.x86_64
Now (as of 2017/01/22):
kernel-3.10.0-514.6.1.el7.x86_64
qemu-kvm-1.5.3-126.el7_3.3.x86_64
libvirt-daemon-kvm-2.0.0-10.el7_3.4.x86_64
It takes 1-2 days for monitoring, to determine whether the situation
has changed since the last update.
