[RFE] add nested virtualization hook vdsm-hook-nestedvt
Last modified: 2018-05-17 18:53:48 EDT
Description of problem: ydary@: There is tech-preview support of nested in RHEL7 we should probably provide this hook as tech-preview as well. ~~~ It did not reach any official EL7 channel: - rpm search in customer portal https://rhn.redhat.com/rhn/channels/software/Search.do - my 4.0-beta hosts: [root@slot-2 ~]# yum repolist -v | grep -i baseurl Repo-baseurl : http://pulp-read.dist.prod.ext.phx2.redhat.com/content/dist/rhel/server/7/7Server/x86_64/rhv-mgmt-agent/4/os/ Repo-baseurl : http://pulp-read.dist.prod.ext.phx2.redhat.com/content/beta/rhel/server/7/x86_64/rhv-mgmt-agent/4/os/ Repo-baseurl : http://pulp-read.dist.prod.ext.phx2.redhat.com/content/dist/rhel/server/7/7Server/x86_64/os/ [root@slot-2 ~]# yum search vdsm-hook Loaded plugins: product-id, search-disabled-repos ============================================================================================== N/S matched: vdsm-hook ============================================================================================== vdsm-hook-ethtool-options.noarch : Allow setting custom ethtool options for vdsm controlled nics vdsm-hook-fcoe.noarch : Hook to enable FCoE support vdsm-hook-macspoof.noarch : Disables MAC spoofing filtering vdsm-hook-openstacknet.noarch : OpenStack Network vNICs support for VDSM vdsm-hook-vhostmd.noarch : VDSM hook set for interaction with vhostmd vdsm-hook-vmfex-dev.noarch : VM-FEX vNIC support for VDSM Name and summary matches only, use "search all" for everything. ~~~ Version-Release number of selected component (if applicable): 4.0-beta
Event if it is tech preview, it's odd to have ability to configure Nested Virtualization in UI but to be forgotten to provide required rpm for customers.
Changing to RFE, it's not missing, it was intentionally left out.
other than the doc text we should likely describe how exactly it is installed and used. should be: yum install vdsm-hook-nestedvt enable nested in Edit Host -> Kernel -> Nested Virtualization reboot host now you can use VMs as virtualization hosts

And if not what is the impact on the rest of the system if a VM is used as a virtualization host? Why is the feature needed? Can any VM become a virtualization host? Is the hook installed automatically on new systems? Can Nested Virtualization be enabled when creating Hosts as well as Editing? Is something else in the UI disabled when this is selected? Or does something need to be selected to activate this? Thanks Emma
ok, installable, virt-host can host another vms vdsm-4.20.6-1.el7ev.x86_64 vdsm-hook-nestedvt-4.20.6-1.el7ev.noarch
(In reply to Emma Heftman from comment #14) > Is there a feature page? nope, it's there for quite some time, only now enabled d/s > And if not what is the impact on the rest of the system if a VM is used as a > virtualization host? there are no guarantees on performance of that nested host. Otherwise there should be no impact on the L0 host, it's "just a VM" from its perspective > Why is the feature needed? testing,demos mostly, I suppose > Can any VM become a virtualization host? yes, as long as the L0 has nested support enabled. > Is the hook installed automatically on new systems? it's not automatically installed, it's just available for installation now as a vdsm hook > Can Nested Virtualization be enabled when creating Hosts as well as Editing? yes. Though it requires the hook installation step, and a reboot of the host to apply the kernel parameter. > Is something else in the UI disabled when this is selected? Or does > something need to be selected to activate this? nope. Just some of the host hw reporting is not accurate/real
