oVirt 4.0 wishlist: VDSM
by Giuseppe Ragusa 21 Nov '15

21 Nov '15

Hi all, I go on with my wishlist, derived from both solitary mumblings and community talks at the the first Italian oVirt Meetup. I offer to help in coding (work/family schedules permitting) but keep in mind that I'm a sysadmin with mainly C and bash-scripting skills (but hoping to improve my less-than-newbie Python too...) I've sent separate wishlist messages for oVirt Node and Engine. VDSM: *) allow VDSM to configure/manage Samba, CTDB and Ganesha (specifically, I'm thinking of the GlusterFS integration); there are related wishlist items on configuring/managing Samba/CTDB/Ganesha on the Engine and on oVirt Node *) add Open vSwitch direct support (not Neutron-mediated); there are related wishlist items on configuring/managing Open vSwitch on oVirt Node and on the Engine *) add DRBD9 as a supported Storage Domain type; there are related wishlist items on configuring/managing DRBD9 on the Engine and on oVirt Node *) allow VDSM to configure/manage containers (maybe extend it by use of the LXC libvirt driver, similarly to the experimental work that has been put up to allow Xen vm management); there are related wishlist items on configuring/managing containers on the Engine and on oVirt Node *) add a VDSM_remote mode (for lack of a better name, but mainly inspired by pacemaker_remote) to be used inside a guest by the above mentioned container support (giving to the Engine the required visibility on the managed containers, but excluding the "virtual node" from power management and other unsuitable actions) Regards, Giuseppe

ovirt-freeipa authentication howto
by Rob Verduijn 20 Nov '15

20 Nov '15

Hi all, I found that for some reason it is hard to find a working example for integrating ovirt3.5 with freeipa using the generic aaa ldap extension. Here's what I did to get it to work: The ovirt os is centos 6 x86_64 All the latest patches have been applied. the ovirt machinet can be a member of the freeipa domain but this is not required for the ovirt-freeipa authentication to work. personally I think its nice to have the ovirt machine under freeipa supervision as wel. the freeipa os is centos7 x*86_64 All the latest patches have been applied. The ovirt environment is configured, up and running. There are two ways of single sign on for ovirt. see https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualiza… This howto is for the first option you require a search account in the freeipa domain. add a user account to the freeipa domain login with that account so it asks you to set a new password for it then reset the experation date for the password to somewhere in the far future with the procedure below # # Add the search account for ovirt to the freeipa domain. # # executed these commands on the freeipa server as root. # # first set the variables export SUFFIX='dc=example,dc=com' export OVIRT_SERVER=ovirt.example.com export FREEIPA_DOMAIN=EXAMPLE.COM export USERNAME=ovirt export YOUR_PASSWORD='top_secret_random_very_long_password' # create an ldif file cat > resetexperation.ldif << EOF dn: uid=$USERNAME,cn=users,cn=accounts,$SUFFIX changetype: modify replace: krbpasswordexpiration krbpasswordexpiration: 20380119031407Z EOF # apply the ldif file # the password requested is the directory admin password, this is NOT the same account as the freeipa admin ldapmodify -x -D "cn=directory manager" -W -vv -f resetexperation.ldif # for the second option also : # add the service for http to freeipa kinit admin ipa service-add HTTP/$OVIRT_SERVER@$FREEIPA_DOMAIN # # The following commands are executed as root on the ovirt-engine machine. # # # first install the required package : # yum install -y ovirt-engine-extension-aaa-ldap # # ovirt configuration files # examples can be found here : # /usr/share/ovirt-engine-extension-aaa-ldap/examples/simple/. # mkdir /etc/ovirt-engine/aaa mkdir /etc/ovirt-engine/extenstions.d # # set the vars again ( exports do not work between vm's) # export SUFFIX='dc=example,dc=com' export YOUR_PASSWORD='top_secret_random_very_long_password' export FREEIPA_SERVER=freeipa.example.com export PROFILE_NAME=profile1 # # create the config files # cat > /etc/ovirt-engine/aaa/$PROFILE_NAME.properties << EOF include = <ipa.properties> vars.server = $FREEIPA_SERVER vars.user = uid=ovirt,cn=users,cn=accounts,$SUFFIX vars.password = $YOUR_PASSWORD pool.default.serverset.single.server = \${global:vars.server} pool.default.auth.simple.bindDN = \${global:vars.user} pool.default.auth.simple.password = \${global:vars.password} EOF cat > /etc/ovirt-engine/extensions.d/$PROFILE_NAME-authz.properties << EOF ovirt.engine.extension.name = $PROFILE_NAME-authz ovirt.engine.extension.bindings.method = jbossmodule ovirt.engine.extension.binding.jbossmodule.module = org.ovirt.engine-extensions.aaa.ldap ovirt.engine.extension.binding.jbossmodule.class = org.ovirt.engineextensions.aaa.ldap.AuthzExtension ovirt.engine.extension.provides = org.ovirt.engine.api.extensions.aaa.Authz config.profile.file.1 = ../aaa/$PROFILE_NAME.properties EOF cat > /etc/ovirt-engine/extensions.d/$PROFILE_NAME-authn.properties << EOF ovirt.engine.extension.name = $PROFILE_NAME-authn ovirt.engine.extension.bindings.method = jbossmodule ovirt.engine.extension.binding.jbossmodule.module = org.ovirt.engine-extensions.aaa.ldap ovirt.engine.extension.binding.jbossmodule.class = org.ovirt.engineextensions.aaa.ldap.AuthnExtension ovirt.engine.extension.provides = org.ovirt.engine.api.extensions.aaa.Authn ovirt.engine.aaa.authn.profile.name = $PROFILE_NAME ovirt.engine.aaa.authn.authz.plugin = $PROFILE_NAME-authz config.profile.file.1 = ../aaa/$PROFILE_NAME.properties EOF # # change owner and permissions of the profile file # chown ovirt:ovirt /etc/ovirt-engine/extensions.d/$PROFILE_NAME-authn.properties chmod 400 /etc/ovirt-engine/extensions.d/$PROFILE_NAME-authn.properties # # restart the ovirt engine # service ovirt-engine restart # # done you can now add freeipa users to the rhevm portal in the users menu # after the users have been added you can assign permissions for them on the vm's # Cheers Rob Verduijn

Allowing a user to manage all machines in a pool
by Nicolás 20 Nov '15

20 Nov '15

Hi, We're running oVirt 3.5.3.1-1, and we're currently deploying some Pools for students and teachers, so each has access to one machine in the pool. Thus, each of them is granted the UserRole in the pool. Now the teacher is asking us to allow him access to all students' VMs via the Web GUI to evaluate their work. Is there a permission to accomplish that? In worst of cases I will detach the VMs from the pool and grant the teacher the UserRole on each of them, but I'd like to know if there's a "cleaner" way. Thanks. Regards, Nicolás

If there's anyone with 1500+ reputation in stackoverflow, I'd be happy if he/she could create an 'oVirt' tag for oVirt related issues, such as http://stackoverflow.com/questions/33775293/how-to-transfer-vm-from-virt-ma… TIA, Y.

[EVENTS] oVirt event about storage domain
by Julian De Marchi 20 Nov '15

20 Nov '15

heya-- I am running a 3.6 cluster using hosted-engine. I have finally got the cluster running and left it over the weekend. Today however in my Events panel in the manager interface I am seeing this entry: The Hosted Engine Storage Domain doesn't no exist. It should be imported into the setup. I go to import data into my cluster and it says there is no data domains to import. In 3.5 this was never an issue and the hosted-engine pool was never visible in the management interface. Would appreciate any help. Thanks! --julian
