Desktop virtualization and thin clients
by Giulio Casella 11 Apr '17

11 Apr '17

Hi, I'm evaluating some thin client to connect to ovirt VMs, used as desktop workstations. I really don't care about native client support, I distribute via PXE a custom linux OS launching remote viewer. I'd like to have good multimedia performance, at a reasonable price. Googling a little, I focused on a couple of vendor: https://www.igel.com and https://www.10zig.com/. Anyone has already tested those vendor products? which model? which is the (approx.) price? Obviously any hint on other vendors are welcome. The scenario is composed of about 1500 VMs, running on ovirt (RHV to say the truth), distributed over 3 datacenters, currently accessed using old (5-7 years) PC, that I'm planning to renew. TIA, Giulio

Python-SDK4: How to list user permissions?
by nicolas＠devels.es 11 Apr '17

11 Apr '17

Hi, I'm trying to get a user's list of permissions, i.e., list all permissions a user have on VMs and VmPools. In SDK3 that was easy as I could run (being 'u' a User object): for perm in u.permissions.list(): vm = perm.get_vm() vmpool = perm.get_vmpool() if vm or vmpool: print "User has some permissions!" In SDK4 I cannot reproduce the same logic. u.permissions returns an empty list ([]). What I have so far is something like this: for u in users_serv.list(): if u.user_name == 'admin@internal': continue vms_service = sys_serv.vms_service() for vm in vms_service.list(): vms = vms_service.vm_service(id=vm.id) ps = vms.permissions_service() for perm in ps.list(): perm_service = ps.permission_service(id=perm.id) getperm = perm_service.get() if getperm.user.user_name == u.user_name: print "Permission for %s" % (u.user_name) if getperm.vm: print "VM: %s" % (getperm.vm.id) if getperm.vm_pool: print "VmPool: %s" % (getperm.vm_pool.id) However, this seems a bit overkill. We have nearly 850 VMs and for a single user this takes about 25 minutes to run. Additionally, it doesn't seem to return any permission, although I know this user has some permissions over 2 VMs (not sure where is it messed up). I also tried using the system_service.permissions_service() but it seems to return only the global permissions. Is there an easier way to do this? Thanks!

More 4.1 Networking Questions
by Charles Tassell 11 Apr '17

11 Apr '17

Hi Everyone, Okay, I'm again having problems with getting basic networking setup with oVirt 4.1 Here is my situation. I have two servers I want to use to create an oVirt cluster, with two different networks. My "public" network is a 1G link on device em1 connected to my Internet feed, and my "storage" network is a 10G link connected on device p5p1 to my file server. Since I need to connect to my storage network in order to do the install, I selected p5p1 has the ovirtmgmt interface when installing the hosted engine. That worked fine, I got everything installed, so I used some ssh-proxy magic to connect to the web console and completed the install (setup a Storage domain and create a new network vmNet for VM networking and added em1 to it.) The problem was that when I added a second network device to the HostedEngine VM (so that I can connect to it from my public network) it would intermittently go down. I did some digging and found some IPV6 errors in the dmesg (IPv6: eth1: IPv6 duplicate address 2001:410:e000:902:21a:4aff:fe16:151 detected!) so I disabled IPv6 on both eth0 and eth1 in the HostedEngine and rebooted it. The problem is that when I restarted the VM, the eth1 device was missing. So, my question is: Can I add a second NIC to the HostedEngine VM and make it stick, or will it be deleted whenever the engine VM is restarted? Is there a better way to do what I'm trying to do, ie, should I setup ovirtmgmt on the public em1 interface, and then create the "storage" network after the fact for connecting to the datastores and such. Is that even possible, or required? I was thinking that it would be better for migrations and other management functions to happen on the faster 10G network, but if the HostedEngine doesn't need to be able to connect to the storage network maybe it's not worth the effort? Eventually I want to setup LACP on the storage network, but I had to wipe the servers and reinstall from scratch the last time I tried to set that up. I was thinking that it was because I setup the bonding before installing oVirt, so I didn't do that this time. Here are my /etc/sysconfig/network-scripts/ifcfg-* files in case I did something wrong there (I'm more familiar with Debian/Ubuntu network setup than CentOS) ifcfg-eth0: (ovirtmgmt aka storage) ---------------- BROADCAST=192.168.130.255 NETMASK=255.255.255.0 BOOTPROTO=static DEVICE=eth0 IPADDR=192.168.130.179 ONBOOT=yes DOMAIN=public.net ZONE=public IPV6INIT=no ifcfg-eth1: (vmNet aka Internet) ---------------- BROADCAST=192.168.1.255 NETMASK=255.255.255.0 BOOTPROTO=static DEVICE=eth1 IPADDR=192.168.1.179 GATEWAY=192.168.1.254 ONBOOT=yes DNS1=192.168.1.1 DNS2=192.168.1.2 DOMAIN=public.net ZONE=public IPV6INIT=no

[Ovirt 4.0 Python SDK] Host fail to move in Maintenance State
by TranceWorldLogic . 10 Apr '17

10 Apr '17

Hi, I was trying to deactivate host via python SDK but found that host is not moving in Maintenance State. In this scenario, I found that I have one additional network added in cluster but not setup on Host. Hence it retrying in background for network sync. Because of this I suspect host is fail to move in maintenance state. Can someone help me how to force via python API to deactivate host ? Or Can I stop background sync of host ? Thanks, ~Rohit

oVirt repositories 101; or everything you wanted to know about oVirt repositories and didn't ask
by Eyal Edri 09 Apr '17

09 Apr '17

Hi oVirt developers and users, Some of you might be familiar with the oVirt repositories and all their flavors, while some of you are just familiar with the official releases. The fact is, we have plenty of them and each has its own role and a right usage. Moreover, we did a significant overhaul on all the repositories in the past months, So hopefully now it will be easier to explain which repo to use when. I'll start with reviewing each oVirt repository and give a bit of background and the logic behind it, how to consume it and the relevant usage for it. For simplicity, I'll review the repositories on the 4.1 release, but it valid for all other oVirt releases ( except 'master' which doesn't have an official or pre-release repositories ). I will also upload this information to the oVirt.org site, but since this is important, I didn't want to wait with the sending this email. *oVirt repositories* *Official repositories* *Desc:* here you can find the official signed oVirt RPMs, immediately after an official release has been done. *Path:* http://resources.ovirt.org/pub/ovirt-4.1/rpm/$distro *Update frequency:* on every oVirt release, usually happens on a monthly cadence. *Release rpm: *http://resources.ovirt.org/pub/yum-repo/ovirt-release41.rpm *Who should use it? * oVirt users, developers or anyone who wants a final and official release *Pre-release repositories* *Desc:* here you can find the pre-release bits of oVirt RC builds, just before they are released. *Path:* http://resources.ovirt.org/pub/ovirt-4.1-pre/rpm/$distro *Update frequency:* usually on a weekly or bi-weekly basis *Release rpm: *http://resources.ovirt.org/pub/yum-repo/ovirt- release41-pre.rpm *Who should use it? * oVirt users, developers or anyone who wants to try out oVirt new version before its out, Keeping in mind this isn't a fully verified release and might still have critical bugs which are not fixed yet. Packages in this repo are verified by automation and checked by humans for basic sanity before publishing. *Nightly snapshot (verified) repositories* *Desc:* here you can find the nightly snapshot of RPMs, which passed basic sanity by our 'oVirt System Tests' framework in the oVirt CI system. *Path:* http://resources.ovirt.org/pub/ovirt-4.1-snapshot/rpm/$distro *Update frequency:* Every night *Release rpm: *http://resources.ovirt.org/pub/yum-repo/ovirt- release41-snapshot.rpm *Who should use it? * oVirt users, developers or anyone who wants to try out oVirt latest bits right of the build oven! We trust our system tests, which already run more than 40 various tests such as 'add host', 'create VM', 'live migration' and more! *** Important note: the snapshot repositories are verified only in master currently, we might do the same for 4.1 soon, as we see no issues with master so far ** * *The above repos should suffice to most usres and developers, but if you feel its not enough and you still need a faster verified repo, look below! * *Advanced oVirt repositories* *Builds artifacts repo* *Desc:* This is a new feature from oVirt 'standard CI' project, where each 'build-artifacts' job is actually a yum repo as well. *Path:* http://jenkins.ovirt.org/job/ovirt-engine_4.1_ build-artifacts-on-demand-el7-x86_64/lastSuccessfulBuild/ artifact/exported-artifacts ( example ) *Update frequency:* after each commit or 'ci please build' comment *Release rpm: *N/A *Who should use it? * oVirt developers who need latest RPMs from another oVirt project and cannot or need not wait for that project`s packages to pass OST". oVirt developers running manual OST job and need to test an open Gerrit patch, using the 'ci please build' command. *Tested repositories* *Desc:* The tested repositories hold all the oVIrt packages which passed CI ( similar to snapshot repos ) and retain also version history for X versions back. *Path:* http://resources.ovirt.org/repos/ovirt/tested/4.1/rpm/$distro *Update frequency:* after each 'build artifacts' job is triggered by any oVirt project and if the packages passed sanity checks *Release rpm: *N/A *Who should use it? * If you want to have latest and greatest oVirt packages and can't wait for the nightly repo. If you are testing upgrades or need more than one version of a pacakge in your repo. *Experimental repositories * *Desc:* Internal CI repos which are a part of the 'experimental' flow which runs OST on each built package. *Path:* http://resources.ovirt.org/repos/ovirt/experimental/ 4.1/latest.tested/rpm/el7/$distro *Update frequency:* after each 'build artifacts' job is triggered by any oVirt project and if the packages passed sanity checks *Release rpm: *N/A *Who should use it? * *No one other than internal CI jobs.* These repos are constantly refreshed and RPMs are being removed from them, so they are very prone to errors, please don't use them. I hope this makes a bit of order in all the repos and how to use them. If you still have questions, please don't hesitate to contact the infra team at infra(a)ovirt.org or just reply to this thread. -- Eyal edri ASSOCIATE MANAGER RHV DevOps EMEA VIRTUALIZATION R&D Red Hat EMEA <https://www.redhat.com/> <https://red.ht/sig> TRIED.
