Is this hash correct?

I took the hash of that file and it is something else:

$ wget http://mirror.nbrc.ac.in/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-1804.iso
$ md5sum CentOS-7-x86_64-Minimal-1804.iso
fabdc67ff3a1674a489953effa285dfd  CentOS-7-x86_64-Minimal-1804.iso

Actually I was just about to send the exact comment. The official repo has only sha1 and sha256 hashes (which is used in systemvmtemplate/template.json) but here the iso_checksum_type is set to md5. Either of those needs to be changed.

[rafaelweingartner]

if the type can be set to sha1 or sha256, please do so. Otherwise, we need to configure the right hash value there.

[khos2ow]

I updated the checksum type to sha1 and double checked that the has is actually valid, as well as the URL.
