[Qemu-discuss] outdated qemu prevents to do live disk snapshot/active block commit (RHEL7.4)

[czezz]

Hi everyone,  this might be more related to RHEL itself than to qemu but mayve 
someone can give me some hints to this issue.    My KVM host is based on RHEL 
7.4 and here are some more details:  # cat /etc/redhat-release  Red Hat 
Enterprise Linux Server release 7.4 (Maipo)   # uname -a  Linux master1 
3.10.0-693.17.1.el7.x86_64 #1 SMP Sun Jan 14 10:36:03 EST 2018 x86_64 x86_64 
x86_64 GNU/Linux   # rpm -qa | grep -i qemu  ipxe-roms-qemu-20170123-1.git4  
qemu-kvm-common-1.5.3-141.el7_  qemu-kvm-1.5.3-141.el7_4.5.x86  
qemu-img-1.5.3-141.el7_4.5.x86  libvirt-daemon-driver-qemu-3.2   Problem:  when 
I want to create a snapshot of VM (hosted on this machine) I get following 
error:  "live disk snapshot not supported with this qemu binary"   What 
I have read/goodle'd, qemu supports "live disk snapshot" starting 
from version 2.0/2.1   Questions:  1. Why RHEL 7.4 keeps outdated 
qemu-kvm-1.5.3 which does not allow to do live disk snapshot/active block 
commit?  2. How to update qemu to the version that supports live disk 
snapshot/active block commit ?   Best regards,  czezz
