RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Donald Douwsma 2018-07-31 07:16:30 UTC 
Description of problem:

Both the Microsoft and Red Hat Hyper-V daemons can installed on a system at the
same time. This seems unlikely to work well and can lead to confusion in the
field.

Steps to Reproduce:

1. Download LIS from Microsoft LIS
   Linux Integration Services v4.2 for Hyper-V and Azure
   https://www.microsoft.com/en-us/download/details.aspx?id=55106

2. Install a version of microsoft-hyper-v from LIS

3. Install a version of hyperv-daemons from RHEL

Actual results:

Both versions of the Hyper V daemons are installed.

[root@rhel7 ~]# rpm -qa | grep hyper
hyperv-daemons-0-0.32.20161211git.el7.x86_64
hypervvssd-0-0.32.20161211git.el7.x86_64
microsoft-hyper-v-4.2.5.3-20180717.x86_64
hypervfcopyd-0-0.32.20161211git.el7.x86_64
kmod-microsoft-hyper-v-4.2.5.3-20180717.x86_64
hyperv-daemons-license-0-0.32.20161211git.el7.noarch
hypervkvpd-0-0.32.20161211git.el7.x86_64

Expected results:

A conflict is detected and neither package can be installed without first
removing the other.

Additional info:

Normally the conflict should be detected between the rpms, but since the 
service unit files and binaries are named differently this does not occur.

[root@rhel7 ~]# grep 'Hyper-V' /usr/lib/systemd/system/*.service
/usr/lib/systemd/system/hv_fcopy_daemon.service:Description=Hyper-V FCOPY daemon
/usr/lib/systemd/system/hv_kvp_daemon.service:Description=Hyper-V KVP daemon
/usr/lib/systemd/system/hv_vss_daemon.service:Description=Hyper-V VSS daemon
/usr/lib/systemd/system/hypervfcopyd.service:Description=Hyper-V FCOPY daemon
/usr/lib/systemd/system/hypervkvpd.service:Description=Hyper-V KVP daemon
/usr/lib/systemd/system/hypervvssd.service:Description=Hyper-V VSS daemon

[root@rhel7 ~]# ls -1 /usr/sbin/hyper* /usr/sbin/*hv*
/usr/sbin/hv_fcopy_daemon
/usr/sbin/hv_kvp_daemon
/usr/sbin/hv_vss_daemon
/usr/sbin/hypervfcopyd
/usr/sbin/hypervkvpd
/usr/sbin/hypervvssd

An explicit conflicts in the spec file may be useful?

'LIS' is completely unsupported by Red Hat, we believe that we have everything required to run on Hyper-V and Azure in-box. We discourage our users from installing LIS, in case something seems to be missing or not working well we need a BZ.
