oVirt gerrit 62965 0 master MERGED node: Add requirement to rng-tools 2016-08-30 05:49:26 UTC

Description Nikolai Sednev 2016-08-02 15:34:45 UTC
Description of problem:
rng-tools not included in NGN RHVH-7.2-20160801.10-RHVH-x86_64-dvd1.iso
Without these tools it'll be impossible to have TPM module working with Random Number Generator in RHEVM.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Deploy RHVH-7.2-20160801.10-RHVH-x86_64-dvd1.iso on host.
2.Check if rpm -qa rng-tools exists.
3.Check systemctl status rngd 

Actual results:
On NGN this rpm is missing and making Random Number Generator functionality impossible.

Expected results:
Package should exist on NGN just like it exists on regular RHEL7.2 and rngd should be running.

Shouldn't vdsm be pulling in rng-tools?

Comment 2 Nikolai Sednev 2016-08-03 12:29:16 UTC
I also see that its missing in latest  RHVH-7.2-20160801.10-RHVH-x86_64-dvd1.iso. I've added the host to the engine after it was cleanly installed from that ISO image.

Comment 3 Martin Polednik 2016-08-04 07:45:56 UTC
TPM hwrng is just one example of hardware rng. There will still be
 a) typical PRNG (/dev/random, seealso #1347642),
 b) any other hwrng (such as proper plug-in RNG generator).

Having rng-tools by default could still be small quality of life improvement.

For VDSM it doesn't make sense to require it.

Comment 4 Nikolai Sednev 2016-08-07 08:57:32 UTC
/dev/hwrng is the default option and if used, in many cases it will be used as /dev/hwrng, mostly because of its HW based, thus much faster from performance side. 

The lack of this component makes impossible usage of "Random Number Generator functionality", which will actually turn all VMs that uses it, to VMs that will be unable to even get started. 

Please consider adding a blocker to this bug.

Hi, all

I have reproduce this bug on redhat-virtualization-host-4.1-20170116.0 as follows:

Steps to Reproduce:
1.Successfully install RHVH new build on my local machine .
2.Check if rpm -qa rng-tools exists.
3.Check systemctl status rngd 

Actual results:
#rpm -qa|grep rng-tools
no message output
#systemctl status rngd 
Unit rngd.service could not be found.

On NGN this rpm is missing and making Random Number Generator functionality impossible.

So I think this bug is not fixed now, I will change status to ASSIGN.



Comment 8 Ryan Barry 2017-01-17 14:54:54 UTC
This is already part of ovirt-release-host-node upstream in 4.1

Comment 11 cshao 2017-02-06 07:07:12 UTC
Test version:

Test result:
The rng-tools package has been added to oVirt Node NG / RHV-H.

# imgbase w
[INFO] You are on rhvh-4.1-0.20170202.0+1
# rpm -qa|grep rng-tools

# imgbase w
[INFO] You are on ovirt-node-ng-4.1.0-0.20170201.0+1
# rpm -qa| grep rng-tools

So the bug is fixed, change bug status to VERIFIED.
