In vdsm.log I can see that my python script exits with status code 0 and that the content seems to be added to the vm definition: Thread-130844::DEBUG::2013-08-21 12:43:52,669::libvirtvm::1520::vm.Vm::(_run) vmId=`79dc3123-4584-4dd9-b0f0-c28ede13d672`::?xml version=1.0 encoding=utf-8?domain type=kvm namecentos6/name snip /cpu payloadspayload type=cdromfile name=unattended.txtcontenthostname: centos6/content/file/payload/payloads/domain But in my vm I can't mount the cd drive: # mount /dev/sr0 /media mount: you must specify the filesystem type Is there a special filesystem I have to specify? Furthermore shouldn't I be able to see the payloads content added to this vm via REST-API? Because I can't. Maybe I'm doing some wrong? Thanks, René That's a neat script. I haven't used it--instead I just send xml to the rest api, something like this, which looks a lot like yours: vm id=6aec2d40-e36f-4b02-ab75-933d93f4cb8b href=/api/vms/6aec2d40-e36f-4b02-ab75-933d93f4cb8b payloads payload type=cdrom file name=meta-data.txtcontentsome content/content /file /payload /payloads /vm To attach the payload via the rest api, note that you'd need to send a put request to /api/vms/uuid rather than pass the xml in the run/start action, because that's not yet supported. Doing this, inside my vm I see: [root@cloud-init-test ~]# blkid /dev/sr1: UUID=2013-08-21-19-39-40-00 LABEL=CDROM TYPE=iso9660 I see - so only via REST-API really means only with REST-API ;) I'll add the payload via put request - thanks a lot! And I can mount it without any problems. You can also check the qemu process listing on the host--for instance, mine shows: /usr/bin/qemu-system-x86_64 [...] -drive file=/var/run/vdsm/payload/29e331f9-42df-46e1-aad1-88101b134606.fe53caf3339d55b2b37a893e19e9f10a.img While the vm is running, you can check that file with `file` (should report ISO 9660), mount it on the host, etc. HTH, Greg ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] received packet with own address as source address
I'd enable STP on all ports, including the port connecting your switch to the school switch. VSDSM configures the ovirtmgmt bridge on installation. The reason I'm suggesting that it's not VDSM at fault but rather the school network having a loop is that you mentioned that you get these messages even with no VMs running. - Original Message - From: H.

Re: [Users] so, what do you want next in oVirt?
Hi Itamar , I would be happy to throw in an idea . I think oVirt is lacking the ability to assign permissions on multiple VMs at once . For example , if I want to grant permissions to a certain user on 30 VMs , I need to do it manually (or with some script). I think this feature is essential for an enterprise aimed product. Also it would be really cool to have an ability to create groups within oVirt and not in the directory, and grant a group permissions on a vm instead of adding them one by one . For example , creating a group called Dev and give the group permissions on all relevant VMs instead of adding each user one by one . Hope to see this feature in the next versions .

Furthermore shouldn't I be able to see the payloads content added to this vm via REST-API? Because I can't. Maybe I'm doing some wrong? Thanks, René That's a neat script. I haven't used it--instead I just send xml to the rest api, something like this, which looks a lot like yours: vm id=6aec2d40-e36f-4b02-ab75-933d93f4cb8b href=/api/vms/6aec2d40-e36f-4b02-ab75-933d93f4cb8b payloads payload type=cdrom file name=meta-data.txtcontentsome content/content /file /payload /payloads /vm To attach the payload via the rest api, note that you'd need to send a put request to /api/vms/uuid rather than pass the xml in the run/start action, because that's not yet supported. Doing this, inside my vm I see: [root@cloud-init-test ~]# blkid /dev/sr1: UUID=2013-08-21-19-39-40-00 LABEL=CDROM TYPE=iso9660 Hm, for some strange reason I can PUT the payloads XML to a specific vm without any errors using REST-API, but it seems to never really update the vm definition (when testing with GET payloads is missing again and no cd in my vm).

Most people probably don't use MTU, and the rest is just explaining the network role icons; so maybe not that useful. if it will be upon click, it means that in order to edit a logical network, two clicks will be required in order to get to the edit dialog, as opposed to one click in the current state and in Eldan's suggestion. maybe having two clicks in order to get to the edit dialog is acceptable, however there may be some solutions for that: one possible solution would be to combine both attached suggestions, i.e. the actions within the hover pop-up, as well as the actions drop-down menu, however it means that there will be some redundancy of the actions availability. That sounds bad to me regardless of the other alternatives. another possible solution is to keep only the gear + down-arrow icon (or maybe only the down-arrow icon), without the actual drop-down menu there, just in order to indicate that there are some options available in that area, and have Eldan's pop-up appear when hovering on that icon (or even on the entire logical-network area, as happens today with the current details pop-up) thoughts? I like the gear icon because it's noticeable and easily recognizable. However, keep in mind that bonds should also have the same icon to keep a consistent design. Now imagine a configuration with several bonds on the left-hand-side and quite a few networks on the right-hand-side; I'm no designer, but it could get cluttered with all those gear icons. It MIGHT be preferable to use the other design (tooltip with action bar) and risk the odd person not easily finding it (no disrespect intended, Jason).

Most people probably don't use MTU, and the rest is just explaining the network role icons; so maybe not that useful. if it will be upon click, it means that in order to edit a logical network, two clicks will be required in order to get to the edit dialog, as opposed to one click in the current state and in Eldan's suggestion. maybe having two clicks in order to get to the edit dialog is acceptable, however there may be some solutions for that: one possible solution would be to combine both attached suggestions, i.e. the actions within the hover pop-up, as well as the actions drop-down menu, however it means that there will be some redundancy of the actions availability. That sounds bad to me regardless of the other alternatives. another possible solution is to keep only the gear + down-arrow icon (or maybe only the down-arrow icon), without the actual drop-down menu there, just in order to indicate that there are some options available in that area, and have Eldan's pop-up appear when hovering on that icon (or even on the entire logical-network area, as happens today with the current details pop-up) thoughts? I like the gear icon because it's noticeable and easily recognizable. However, keep in mind that bonds should also have the same icon to keep a consistent design. Now imagine a configuration with several bonds on the left-hand-side and quite a few networks on the right-hand-side; I'm no designer, but it could get cluttered with all those gear icons. It MIGHT be preferable to use the other design (tooltip with action bar) and risk the odd person not easily finding it (no disrespect intended, Jason). I have no idea, however, if it's gonna be just the odd person or most people. I'd love to hear others' opinions. Having not used bridging/multiple VLANS prior to my experimentation with ovirt, it's always been the network interface itself that I have configured with IP/subnet/etc (eg. /etc/sysconfig/network-scripts/ifcfg-eth0). Most of my machines (hundreds) have single network interfaces, and I've never needed to use bonding/bridging/etc which kept my network configuration very simple. After experimenting with oVirt, and doing my share of reading, I certainly understand the concept of logical networks and their configuration with oVirt, and yes, it all makes a lot of sense NOW (well, except for the fact that really when it comes down to it, the Linux configuration for anything but basic networking is, in my opinion, anything but intuitive.) Nonetheless, please keep in mind that a concept which might be completely crystal clear to someone who uses it on a daily basis might be a little less intuitive to someone who is using it for the first time. Fortunately, I've got *plenty* of patience. :) Regards, Einav Thanks for your help! Jason. ___ Users mailing list Users@ovirt.org
Re: [Users] Setup Host Network dialog - actions availability [ux][BZ#984737]

We have a suggestion from Eldan (see attached HostSetupNetworks-HoverPopUp.png) which was described in the BZ (comment #3) and seemed acceptable by the reporter (comment #4), however IIUC - one of the main pain points described in the BZ was the fact that the user could not find the option to Edit the connection properties since he was looking in the wrong place, and needed to hover on the correct place, in order to find that option. So although the idea is somewhat helpful, my concern is that this solution is not enough (comment #5). Another proposal from Malini (comment #6) is to add an actions drop-down menu in the form of a small gear icon-button - see attached HostSetupNetworks-DropDownMenu.png. This proposal addresses my concern, however I have a question about another concern with this solution: would the actions-drop-down menu-items panel be revealed appear upon click or upon hover? if it will be upon hover, it might seem weird/be conflicted/be somewhat confusing with the hover functionality that reveals the logical-network details pop-up. If this proposal is accepted (see my comments below about both proposals), one solution might be to get rid of the network details tooltip. Most people probably don't use MTU, Just a FYI there Lior; we do:) And when 10GbE becomes available, Jumbo Frames is going to be required to use all that bandwidth. Otherwise you are capped at about half(500MB/s as opposed to 1,2GB/s). /Karli and the rest is just explaining the network role icons; so maybe not that useful. if it will be upon click, it means that in order to edit a logical network, two clicks will be required in order to get to the edit dialog, as opposed to one click in the current state and in Eldan's suggestion. maybe having two clicks in order to get to the edit dialog is acceptable, however there may be some solutions for that: one possible solution would be to combine both attached suggestions, i.e. the actions within the hover pop-up, as well as the actions drop-down menu, however it means that there will be some redundancy of the actions availability.
