virt-manager allocates huge amount of ram when using http install

Description of problem:
virt-manager allocates over 1.5GiB of virtual memory after two or more virtual machines are created: Network install (http), ram 1800MB, storage LVM lv
guest os: rhel-7 "latest"
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. choose network install
2. specify http URL (rhel-7 in my case)
3. set RAM 1800MB
4. I've used LVM
5. install os, don't turn it off, remove it (without disk if you want)
6. repeat at least once (with disk from step 5 if you have it)
virt-manager uses over 1.5GiB of virtual memory
considerably lower memory consumption
VM specs after installation:
<type arch='x86_64' machine='pc-i440fx-rhel7.0.0'>hvm</type>
I can reproduce this issue with:
Steps are the same as description.
*** Bug 1139125 has been marked as a duplicate of this bug. ***
can it still be reproduced on RHEL-7.1 with the latest pygobject version? I am going to move it to 7.2
Since there were no response, whether the issue is still there and I've tested it right now and the memory usage by virt-manager after several network install is consistent, I'm closing this bug as fixed by rebase.
One more thing to add, the usage of virtual memory will be always significantly larger, because it contains all shared libraries. The RES (Resident Memory Size) is the value you should check, because that's the current memory usage.
I've just looked at the attachment and actually this wasn't bug at all, because the real usage is about 216 MiB, which isn't that much. I'm closing this as not a bug.
