[PVE-User] Hierarchical pools
Hello, I would like to suggest a feature, or to know how do you do to (if you do it), when want to add the VMs to more than a pool. As an example, if I have several pools of VMs, say "Development", "Systems" and "Lab", I would like to let some users/groups both from developer and system groups to control the VMs from pool "Lab" with some elevated privileges like poweroff, CDROM, etc to install and configure the VM before entering production. I cannot see how to acomplish this, because one reource (VM/storage) can belong only to one Pool. As far as I can see, there are two options, let the pools be hierarchical or let the resources belong to more than one pool. Can this feature be useful enough to suggest it to the Proxmox team? Anyone achieve this with some workaround I didn't thought? Best, -- [cid:part1.74F14D67.C6327600@dltec.net] Angel Docampo Datalab Tecnologia, s.a.

Correct me if I am wrong but below solutions (Windows TS and Linux X

Windows Terminal services and Linux X desktops are totally different and
can be implemented on every virtualization platform (or bare metal).
The advantage of using Proxmox with Spice is the integration between the
virtualization environment and the (thin) client's desktop/experience.
VDI is more appealing on platforms like VMware Horizon where desktop and
applications are virtualized and management of images is much easier
(with high cost of course :-) )
Exactly. And that was my initial question - if anyone has any idea of
how to implement this with Proxmox or if he already has done this.
AFAIK Redhat provides some kind of KVM/SPICE-based solution, although I
doubt that it's ready for production?
Best Regards,
Hermann
Well, I wrote about x2go client because I found it better in network
traffic than spice client itself.
Two years ago we implemented a very simple spice-based application which
asked for a credentials and connected to proxmox using those credentials
and then it shown the VMs where that user could connect to, as many
users only have one VM (or VDI in this case), the desktop showed directly.
That was done with bash and zenity mainly, on the forums is said how to
download the proxmox ticket from the command line and use it as
parameter to remote-viewer.
So, if you want a spice approach, it can be done by you with some work,
I do not know if Proxmox team will develop a desktop client for this in
the future, but it can be acomplished with some bash scripting or using
promox API.
Anyway, I reiterate, spice client is... "network expensive", and you'll
need a good connection to work properly, in a LAN it shouldn't be a
problem, but for remote clients is unbearable.

Re: [PVE-User] VDI on Proxmox anyone?
Hi there! I have set up proxmox as VDI infrastructure for a while and it works great. While the experience is quite good on enterprise environments, is true that online videos are too expensive in network terms. What I'm using to connect to the VDIs is x2go TCE (http://wiki.x2go.org/doku.php/wiki:advanced:tce:install), is based on nx and it's jpeg compression or whatever it uses reduces it's bandwidth to a level you can connect even through a DSL connection from home.

Re: [PVE-User] VDI on Proxmox anyone?
Oh, I forgot to say we mainly use Linux as desktops, so no need to golden image as linux is multi-user, so I need only to upgrade one VM. We have some windows server with terminal services and with some windows-only software on them, but as said, VDI infrastructure relys on linux desktops ;) Anyway, you can have windows VM and access through a thinclient booting x2go (or other lightweight linux distro bootable via PXE) and access your windows VDI throught rdesktop instead of x2go client, I've just tried the same youtube video both in windows and in linux and while in linux trought x2go protocol the video seems smoother while not in full screen, seems that rdesktop protocol in windows handles full screen videos a bit better... anyway, in a enterprise environment, where watching videos is sporadical and they can be seen perfectly in a windowed size, all virtual environments, from KVM to commercial, offers a pretty but limited performance. As you can see, my approach is different from yours: instead to have one VM for each users (even each VM is a linked clone from a template) I have one VM for many users, one linux and one windows. In linux is free and in windows I must use TS licenses (well, if you're legal, you should use them also in windows clones). The benefeits in having several users on the same VM is shared memory, resources from the VM are shared amongst the users, but in echange having a machine-user ratio of 1:1 you can isolate the processes, in both approaches, you only must maintain only one VM.

Node1: OSD1 + Monitor Node2: OSD3 + Monitor Node1: Monitor Only Node1 Node2 are connected via Dual Bonded 1GB Ethernet Node3 Only has 1GB Ethernet Bonded interfaces on linux are active-backup, so you have a 1Gb connexion on the storage side. Consider to upgrade to a faster ethernet/fiberchannel/infiniband. You will have no problems with your intel nuc as quorum node, I have a 512MB RAM VM with 8GB HDD with debian and proxmox for that purpose. -- *Angel Docampo * *Datalab Tecnologia, s.a.* Castillejos, 352 - 08025 Barcelona Tel. 93 476 69 14 - Ext: 706 Mob. 670.299.381 ___ pve-user mailing list pve-user@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user

Have got a test setup running on a 2 node cluster (using external USB Drives!) that works surprisingly well :) and I must say it was very easy to setup. 1. I wanted to implement a distributed/replicated file system. Is GlusterFS the best choice for a 2 node system? Would it be easy to add a third node later? 2. When launching a VM off Node 1 or Node 2, is it accessing the local hard disk directly, or does it all go through a network share? Our network is only 1GB and it would be nice to take some of the load off it. Should I be asking these question on the forum rather than the list? Thanks, -- Lindsay ___ pve-user mailing list pve-user@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user I'm using successfully Proxmox with GlusterFS. Each proxmox node is also a gluster node, and now I have two nodes (using a third proxmox node on vmware for proxmox quorum). I must say it works pretty nice, I even provide Windows VDIs with this system. Adding a third (with a fourth -it's a replica, you know-) and more nodes, it's pretty straight forward. Just prepare them, add to the gluster and the data will be rebalanced, with a 10Gb network, the data will be rebalanced hugely faster than with a 1Gb network. I also suggest to you to use a better network because glusterfs writes are synchronous. The benefit of this is that if one node comes down, all the information is in the other node, so there are chances that the VMs even didn't notice when a node comes down. When you write on gluster, even you have mounted it using the IP of one of them, the writes are randomly (not really random) send to any node, and then, replicated amongst them, it's the internal operation. You could set up a georeplica instead a replica, designed to replicate two gluster clusters amongst remote offices, and then you could use your 1Gb network to make asynchronous writes. The cons I see are you don't have *exactly* the same data on the both clusters at each time, and in case of a node comes down, you should reconfigure all VMs to point their disks to the other GlusterFS, because they are two different clusters. So, summarizing: Yes, you can use gluster in a two-node gluster setup, I do not know if Ceph its better though, I can only share my positive experiences with gluster. I would recommend you to use a 10Gb network dedicated for gluster communication, it will be useful to replicate data synchronously and essential for rebalance the data when in a future you will need to add more nodes. -- *Angel Docampo * *Datalab Tecnologia, s.a.* Castillejos, 352 - 08025 Barcelona Tel. 93 476 69 14 - Ext: 706 Mob. 670.299.381 ___ pve-user mailing list pve-user@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user

Mmm, that script is damn similar to my first one... now it has
evolved to a python one, taking the benefits of proxmoxer wrapper
(https://pypi.python.org/pypi/proxmoxer/0.1.4).
Furthermore, the bash script does not work in a cluster and you do
not know exactly in which node the VM is. That's why I used one of
the nodes as a broker
Anyway, the API documentation hasn't changed since months, so I
guess you didn't change the API, don't ypu?

Re: [PVE-User] GlusterFS VM failover
Hi there, Mmmm, if you use /etc/fstab or glusterfs client, you will be accessing the gluster via FUSE. And that s*cks. I do a trick on my proxmox cluster, as well gluster cluster. I do have one 10Gb interface dedicated to gluster on each node, and another 1Gb interface dedicated to proxmox cluster. So, in hosts, my config is more or less this one. #PROXMOX NODES 10.0.0.1 pve01 10.0.0.2 pve02 #GLUSTER NODE 192.168.100.10 g01 192.168.100.20 g02 Until this point, completely normal, now, on the first node (pve01/g01) y put on hosts 192.168.100.10 gluster And this other hosts line on node pve02/g02 192.168.100.20 gluster So, on proxmox GUI I mount gluster:VOLUMENAME. Each node mounts its own mountpoint and on the redhat cluster, the resource is called the same: gluster. Its a trick if your virtualization nodes are also storage nodes, which is my case. Hope it helps. El 28/01/14 17:41, Leslie-Alexandre DENIS escribi: Hello, As I think that I reply to my own question after searching in GlusterFS documentation, I'm wondering if anybody from Proxmox's staff here can guide me. In fact, GlusterFS has an option to specify a backup node to the primary one. In a replicated setup, it permits to be sure that the client points to the healthy node. It's specified in the mount command or /etc/fstab on the client side, like : # mount -t glusterfs -o backupvolfile-server=volfile_server2,fetchattempts= 2,log-level=WARNING,log-file=/var/log/gluster.log server1:/testvolume /mnt/glusterfs If backupvolfile-server option is added while mounting fuse client, when the first volfile server fails, then the server specified in backupvolfile-server option is used as volfile server to mount the client. Basically my question is : Where can I find the GlusterFS client mount entry on Promox ? And do you plan to implement that functionality in the GUI and qemu ? (It would be awesome) For anybody on that topic, you can find more information here : - http://www.jamescoyle.net/how-to/439-mount-a-glusterfs-volume or in the official Administration Guide Thanks, Regards ___ pve-user mailing list pve-user@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user -- Angel Docampo Datalab Tecnologia, s.a.

Re: [PVE-User] Several issues with gluster as storage.
El 27/01/14 14:38, Leslie-Alexandre DENIS escribi: Hello Angel, Did you figure it out why you had timeout problem ? Yes, I did. The main problem was the underlying filesystem. I do not know why, but XFS does not thin provision the space of the hard disk when create the virtual machine. Then proxmox times out at 30 seconds, or so. Because it should be matter of one or two seconds. Changing it to ext4 solved the main problem. Another issue, even with ext4, was the timing when in the gluster cluster (2 nodes), there were one node down. There is a bug on gfapi that times out the proxmox cluster when trying to start a VM on that gluster storage. While gluster developers fix that bug. I lowered the value on /proc/sys/net/ipv4/tcp_syn_retries from 5 to 3 to reduce the time necessary to start the VM and now everything works, Regards Regards, Le 11/12/2013 17:28, Angel Docampo a crit : Hello, There is no special topology between the nodes, it's a 10Gb dedicated segment only for that purpose.

[PVE-User] Several issues with gluster as storage.
Hi there, I'm having several problems with using gluster as a storage. I'm using a gluster replica 2 between two buildings, the connection is 10Gb. I can access gluster and write so far so good. But when using proxmox the problems arise... I cannot upload iso files (I think I've readed on the forum that its a bug) and in fact it's a minor issue. The problem comes when I want to create a VM. It takes a long time (I guess depending the hard disk size) and if I try to access via ssh when it is trying to create the VM, when I cd to the glusterfs mountpoint it seems to be stalled (I cannot do a double-tab for autocomplete the name, for instance). After a while, the GUI shows, TASK ERROR: create failed - unable to create image: got lock timeout - aborting command I can create the VM on a local storage (I didn't try a NFS share, iSCSI or another network destination) flawlessly, and then move the disk to the gluster storage without problems. I can even mount via FUSE the gluster and the I CAN create the VM on it (but it is considered then a local storage and I cannot do a live migration, etc). So, there is any problem with replicas? I tried on a distributed-only gluster on the lab and it worked perfect, but on my client's house I'm facing this... Any idea? I can post any log if you want, but I would also know your experience with this scenario. I have quite experience with gluster, so I'm pretty sure that this gluster is working as it should.

You'll need to write some code and play with the proxmox API in
order to get a working "shorcut". It's quite easy, but for each
connection, you will need to log into the proxmox and get a valid
ticket, the the remote-viewer application will connect to the

[PVE-User] Custom fencing scripts
Hi there, I wrote two scripts in order to turn off the nodes with my fence devices, two APC smart-ups 1400, accessible only via telnet or web and each connected to one node, and IBM bladecenter which blade9 is my third node.

It's my first attempt to make fencing work, so I have some doubts you may resolve... Those two scripts are named fence_apc_expect and fence_bladecenter_expect, the first will have only one parameter, the IP of the mangement network interface of the UPS, and the second script, two parameters, the management network IP of the bladecenter and the number of the blade we want to turn off. I won't pass the user and password of the UPS/Bladecenter because they are embedded on the script.

There are another proxmox cluster in the same network and it's working (it was very painfull also to install, but once I realized the problem was unicast and the mtu size, it works very well, except when adding a node, that always is another pain). So, I would like to explain how I'm doing this and perhaps I'm pretty obfuscated to see what is happening. I've installed two debian 7.1, LVM partitions (not necessary, but I did it anyway), and installed proxmox. The servers works as expected separately. The server p01 have the IP: 192.168.200.197 The server p02 have the IP: 192.168.201.191 The two networks are visible each other, and as cluster protocol is udp, it should work. Am I wrong? Then on p01, I've created the cluster with pvecm create testcluster, it worked I've copied /etc/pve/cluster.conf to /etc/pve/cluster.conf.new, increased the version number and add transport=udpu to the cman section and added the section totem netmtu=1400 / (I tried without it also). Then I've activated the new configuration throught the GUI. I've double checked /etc/hosts to assure they resolve the names through this mechanism. Then on p02 I tried to add the node with pvecm add p01 (also tried with IP and also tried this command from p01, both with hostname and IP of the p02 node). root@p02:~# pvecm add p01 root@p01's password: copy corosync auth key stopping pve-cluster service Stopping pve cluster filesystem: pve-cluster. backup old database Starting pve cluster filesystem : pve-cluster. Starting cluster: Checking if cluster has been disabled at boot... [ OK ] Checking Network Manager... [ OK ] Global setup... [ OK ] Loading kernel modules... [ OK ] Mounting configfs... [ OK ] Starting cman... [ OK ] Waiting for quorum... [FAILED] Waiting for quorum... I had to issue, on the master, pvecm e 1 to resolve the quorum error. Running like a charm now. That is in the HOWTOS. Ric Thank you very much. It's not so easy, yet even /etc/pve now was writeable, and cluster.conf was the same in each node, it still showed a split brain situation. But your advice gave me some direction to investigate. I found that pvecm e 1 its the same than edit cluster.conf and add the parameter expected_votes=1 on directive cman. I also added the parameters transport=udpu (I have no multicast support) and two_node=1 and rebooted the main node. After that, I could add the second node and restart pve-cluster and cman daemons on both nodes (or restart the machines) in order to see them clustered. It has been pretty hard to made it work, but I think now I got the concepts.

[PVE-User] Impossible to create two nodes cluster.
Everytime I need to create a cluster in proxmox I suffer a bit PITA. But now I simply can't do it. I've reinstalled several times and deleted and recreated the cluster again and again. No luck. Multicast does not work in this network, so I used unicast. There are another proxmox cluster in the same network and it's working (it was very painfull also to install, but once I realized the problem was unicast and the mtu size, it works very well, except when adding a node, that always is another pain). So, I would like to explain how I'm doing this and perhaps I'm pretty obfuscated to see what is happening. I've installed two debian 7.1, LVM partitions (not necessary, but I did it anyway), and installed proxmox. The servers works as expected separately. The server p01 have the IP: 192.168.200.197 The server p02 have the IP: 192.168.201.191 The two networks are visible each other, and as cluster protocol is udp, it should work. Am I wrong? Then on p01, I've created the cluster with pvecm create testcluster, it worked I've copied /etc/pve/cluster.conf to /etc/pve/cluster.conf.new, increased the version number and add transport=udpu to the cman section and added the section totem netmtu=1400 / (I tried without it also). Then I've activated the new configuration throught the GUI. I've double checked /etc/hosts to assure they resolve the names through this mechanism. Then on p02 I tried to add the node with pvecm add p01 (also tried with IP and also tried this command from p01, both with hostname and IP of the p02 node). root@p02:~# pvecm add p01 root@p01's password: copy corosync auth key stopping pve-cluster service Stopping pve cluster filesystem: pve-cluster. backup old database Starting pve cluster filesystem : pve-cluster.

I can see the p02 node on the p01 GUI (with a red light), but I have no access.

Re: [PVE-User] md installer?
I think, I may be wrong, that the Barebone Installer is not customizable at all, and won't be. If you want to customize your partition layout, you must install first Debian, and then add the proxmox repos and install it. As explained on the wiki. http://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Wheezy I did it myself and is really painless, so I suggest to you to try out.
