It may work, but we don't support 3.6 for a while and I'm not sure what issues you may encounter.

We are using oVirt engine 3.6. How can I prevent upgrade my hosts with CentOS 7.2 to unsupported 7.3? Thx.

I would do this way

yum clean all

modify your repo fies in /etc/yum.repos.d

- verify CentOS-CR is disabled

- at least in

CentOS-Base.repo

where you don't have "enabled=0" (so both where there is no enabled=.. line and where enabled=1)

comment mirrorlist and uncomment baseurl

in baseurl line substitute the word

$releasever

with

7.2.1511

try a yum update and verify that no 7.3 packages come in.

The problem is that epel repo don't track minor versions, so that if you have an update in epel that requires a 7.3 package you would get dependency error.

or you can disable also epel in the mean time if this is the case....

HIH,
