Thanks for sharing your findings Nicolas. I'll base my vote on that.
Considering the vote is based on:
"- On CloudStack's Installation Guide > Host KVM Installation[²], we add a
section guiding users to install the qemu-kvm-ev binaries, if they are
using CentOS 7.
- The packages that we will guide users to install will be the latest
provided by the official CentOS site[³] (the current latest version is
'2.12.0-44.1.el7_8.1.x86_64')."
+1 (binding) to doc changes limited to CentOS7 on using qemu-kvm-ev. It's worth
noting that qemu-kvm-ev (the -ev releases) isn't available for el8 anymore?
This may need double-checking as I couldn't find them on first attempt or also
search via yum/dnf [1]. We need at some point revisit the QIG, add QIG for
Ubuntu 20.04/22.04 (soon) and EL8 (rocky/alma/rhel8).
I would see the PR as a separate thing than this vote and I don't see why
Daniel's PR can't be accepted if he addresses the comments, with the following
suggested guidance and checklist:
* The vote is just for docs and shouldn't be used to justify the removal or
regression of stock qemu support in el7/centos7.
* Please fix the regression found in Nicolas's testing and address other
outstanding comments on the PR.
* Regression test via smoketests in addition to any manual tests can ensure
it works for following environments:
* CentOS7 with stock qemu
* CentOS7 with qemu-kvm-ev
* CentOS8 with stock qemu
* Test Ubuntu 18.04/20.04 and OpenSUSE kvm env
* Misc: Since the PR changes are around storage/snapshot, we should try
to cover for local storage, nfs/qcow2, ceph/rbd (and scaleio/raw) etc.

Subject: Re: [VOTE] CentOS 7 KVM binaries
Hi all,
After the concerns on the thread I have tested PR 5297 on CentOS 7 with stock
qemu-kvm binaries to reevaluate my vote. I found only one regression around
snapshots: taking volume snapshots for running VMs does not work anymore as
qemu complains with error: Operation not supported: live disk snapshot not
supported with this QEMU binary.
I agree with Paul and Rohit in this case as a drop of support for users on
CentOS 7 with stock qemu-kvm, so my vote will be -1 in this case. But would be
+1 if we can fix the regression for this specific case as the rest of the
operations are working fine.
Regards,
Nicolas Vazquez

Gabriel, Daniel, the pull request (code change) is new information for me
https://github.com/apache/cloudstack/pull/5297
There's also no rule or guidance that people can't discuss on a voting thread,
I find the terms used to refer to that "polluting" derogatory. The vote also
did not mention the PR and its implications, I'm sure most people on the thread
have voted only on doc changes. Thanks Gabriel to sharing the background, it
also explains what led Daniel to start the vote.
Daniel, on the logistics of voting you may want to read the project bylaws and
get familiar with the terms.
All, I'll need to find some time and then get back to this thread after
reviewing pros and cons of the PR and its implications after some due
diligence. Alternatively, I'm happy if some other PMC can do the due diligence,
I'll then add my vote based on PMC findings.
Regards.

Subject: Re: [VOTE] CentOS 7 KVM binaries
@Gabriel has summarized everything very well.
This proposal only adds a requirement (makes it clear) in our
documentation for KVM + CentOS 7 (please, refer to the discussion
thread[¹] to understand why it is necessary), which is what everybody
(according to the discussion we had in the mailing list) is already
applying in production environments. Therefore, we would only make this
requirement clear to everybody, which would in turn enable us to move
forward with KVM improvements (such as my PR that improves the snapshot
process[²]). It (the discussion we had) never addressed dropping support
for CentOS 7.
Regarding Rohit's comment ("However, assuming Daniel has followed the
bylaws and is suggesting this as a technical change that removes support
in source code or releases..."), I never suggested a drop of support for
CentOS 7. I don't know how that conclusion was derived.
To emphasize, this proposal do not address dropping support for CentOS
7. Please, review the discussion thread[¹] and the proposal and
reconsider your votes.
Best regards,
Daniel Salvador
