Re: [one-users] Using OpenNebula for Linux desktops
Dear Carlo, Thanks for your suggestions, I will add my comments and details below regarding the various performance points you mention. So yes I am using QXL as video driver, for that purpose I have added to my ONE template the following RAW data: devicesvideomodel type=qxl heads=1/model/video/devices As far as I remember AIO=native is the default and as such I should already be using native AIO. As data storage I am using an NFS server with a SATA JBOD in hardware RAID6 (HP hardware). I am sharing the datastores from that server using the following export: /data/one/datastores/101 192.168.1.0/24(rw,sync,no_subtree_check,root_squash) Then on my ONE hosts I mount them using the following fstab entry: 192.168.1.2:/data/one/datastores/101 /var/lib/one/datastores/101 nfs soft,intr,rsize=8192,wsize=8192 Regarding the cache setting in the ONE template I always use none as I read quite often that in most of the cases cache should be set to none. Using iotop (great tool btw!) to measure IO activity and using the image at the same time does not show much IO activity so I don't think IO is the bottleneck, also it is the only VM I am running on a test setup. Other info to mention maybe: I am using a test VM with 4 GB of RAM and 4 CPU running on a host with dual Quad-Core Intel E5504 @2GHz (approx. 3 years old CPU). The resolution I am using for the desktop is 1680x1050. For your reference, below is the full KVM process which is running on the ONE host: /usr/bin/kvm -S -M pc-1.1 -enable-kvm -m 4096 -smp 4,sockets=4,cores=1,threads=1 -name one-70 -uuid 8429d2bf-553f-d503-83e4-c44fc626de5c -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/one-70.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=/var/lib/one//datastores/101/70/disk.0,if=none,id=drive-virtio-disk0,format=qcow2,cache=none -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -drive file=/var/lib/one//datastores/101/70/disk.1,if=none,id=drive-ide0-0-0,readonly=on,format=raw -device ide-cd,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -netdev tap,fd=20,id=hostnet0 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=02:00:b9:0f:1f:29,bus=pci.0,addr=0x3 -spice port=5970,addr=0.0.0.0,disable-ticketing -vga qxl -global qxl-vga.vram_size=67108864 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 Let me know if you need any more infos...

First of all, if you use SPICE as a protocol use QXL as the KVM video card, it will provide a substantial speedup (the emulated video card will be much more intelligent and the job of protocol compression will be much simpler). Then, IO speedup is the second low-hanging fruit. We use aio=native, and this alone substantially increases io rates. The next step depend on the kind of datastore you use- NFS, an external SAN, etc. If you can provide some additional details I can give some more options. For example, for machines that require high random R/W we use cache=none as it does decrease double buffering, thus improving performance. You can use iotop on the machine that executes the KVM process to check how much does it write, and why. In our tests, using OpenNebula on top of the MFS distributed filesystem we easily get VDI performance near to that of the hardware with limited tuning. regards, carlo daffara CloudWeavers - Messaggio originale - Da: ML mail mlnos...@yahoo.com A: users users@lists.opennebula.org Inviato: Lunedì, 27 gennaio 2014 16:51:19 Oggetto: [one-users] Using OpenNebula for Linux desktops Hi, I am currently evaluating OpenNebula for running KVM virtual machines which will be used as Linux desktops with the SPICE protocol.

The desktop reacts quite slowly even basic things like displaying the main menu and using the terminal even on a 1 Gig LAN.

[one-users] oneacct: accounting information not correct?

Re: [one-users] Accounting of storage used by user
Hi, I see three ways to approach storage billing: - Bill according to the available storage (limit set in the quotas). - Bill the storage used by the running VMs. This was not possible before 4.4, the DISK/SIZE was added for the storage scheduling. Now you can do this: $ oneacct -u 0 -x | xpath -e /HISTORY_RECORDS/HISTORY/VM/TEMPLATE/DISK/SIZE - Bill the DS usage. This usage is tracked in the user quotas, but we don't keep a history for the changes made here. You could create a script to store the user quotas information in a database with a timestamp, and trigger it with a hook [1] on image create and image remove.

Re: [one-users] Confused about VNC ports with the KVM hypervisor
The way to specify VNC ports in OpenNebula is the TCP port, not the VNC port number. This is passed to libvirt that will convert it to VNC port (-5900) as this is the way qemu/kvm wants it. From libvirt documentation (http://libvirt.org/formatdomain.html#elementsGraphics): --8-- The port attribute specifies the TCP port number --8-- From qemu documentation (http://wiki.qemu.org/download/qemu-doc.html): --8-- 'host:d' TCP connections will only be allowed from host on display d. By convention the TCP port is 5900+d. Optionally, host can be omitted in which case the server will accept connections from any host. --8-- On Thu, Jan 23, 2014 at 7:05 PM, Gerry O'Brien ge...@scss.tcd.ie wrote: Hi, I'm a little confused about VNC ports with the KVM hypervisor.

I've found out that CloudInit writes a correct /etc/network/interfaces file with a static address, however, the machine somehow ignores this file and keeps sending DHCP requests without getting an answer (which is intended since we don't use DHCP in the VM's network). # virt-cat one-42 /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.129.4 network 192.168.128.0 netmask 255.255.254.0 gateway 192.168.128.1 # virt-cat one-42 /var/log/syslog | tail -6 Jan 28 12:42:44 ubuntu dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 21 (xid=0x1080a577) Jan 28 12:43:05 ubuntu dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 13 (xid=0x1080a577) Jan 28 12:43:18 ubuntu dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 20 (xid=0x1080a577) Jan 28 12:43:38 ubuntu dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 1 (xid=0x1080a577) Jan 28 12:43:39 ubuntu dhclient: No DHCPOFFERS received. Jan 28 12:43:39 ubuntu dhclient: No working leases in persistent database - sleeping. Does anybody know how the VM template needs to be configured in order to get it working?

Re: [one-users] Accounting of storage used by user
Hi, Thanks for the tips on accounting the storage of a user. I wasn't aware that the XML output has so much more information.. Actually there is everything I need in there, even IP information. That's perfect!

Now you can do this: $ oneacct -u 0 -x | xpath -e /HISTORY_RECORDS/HISTORY/VM/TEMPLATE/DISK/SIZE - Bill the DS usage. This usage is tracked in the user quotas, but we don't keep a history for the changes made here. You could create a script to store the user quotas information in a database with a timestamp, and trigger it with a hook [1] on image create and image remove.

I have a CentOS VM image to which I added the opennebula-context package from the OpenNebula yum repository. The VM starts normally and I can configure networking and passwordless SSH whitout any problem. Now I wanted to take contextualization a step further: I want to add my own scripts to the ISO file that is mounted to the VM filesystem. I uploaded a 'init.sh' script to the files datastore with type 'CONTEXT'. This init.sh script seems to end up in the ISO file that is deployed with the VM and if the /etc/init.d/vmcontext script has run on the VM, it mounts the ISO file on /mnt. However, it looks like my init.sh script (which is in /mnt/init.sh) is never executed ... The /etc/init.d/vmcontext script only seems to execute the scripts in the /etc/one-context.d directory. From the documentation [1], I understood that if my init script is called init.sh, I wouldn't have to specify the INIT_SCRIPTS attribute in my VM template. I have the feeling that I'm missing something; maybe my understanding of advanced contextualization is not correct?

Re: [one-users] Vlan template
It seems like the command to add trunk is almost identical to adding vlan: - vlan (ie. Access-port) : ovs-vsctl set port vnet0 tag=Vlan1 - trunk : ovs-vsctl set port vnet0 trunks=VlanID1,VlanID2 Would it be possible to adjust command to add trunk port with list of VLANs if multiple VLAN Ids listed in the Virtual Network’s VLAN field? -- Thank you, Dmitri Chebotarov VCL Sys Eng, Engineering Architectural Support, TSD - Ent Servers Messaging 223 Aquia Building, Ffx, MSN: 1B5 Phone: (703) 993-6175 | Fax: (703) 993-3404 On 1/28/14, 12:23 , Dmitri Chebotarov dcheb...@gmu.edu wrote: Hi guys Have you found solution for how to add trunk interface?
