Nic Bonding in OVM Server

Hi
I am setting up a OVM environment where I want to implement NIC bonding. I want to bond eth1 and eth3, the IP address are showing against xenbr1 and xenbr3. Please let me know the steps of doing this.
Thanks

Cluster Not Available error when booting OVM server DOM0 from USB

Hi all,
I have been wanting to run OVM 2.2 from a USB stick for a while now. I ran through the install CD today and saw there was a 'minimal USB install' option on the installation screen. So I plugged in a 4GB USB stick, rebooted, and ran the USB install.
After a while, the install completed, OVM booted up perfectly it seemed, and I was happy.
The server had no local storage apart from this USB stick as we are going to be hooking it up to an iSCSI target for guest VM storage.
This was a new lab setup, so I got the VM Manager running on another system, connected to the USB booted OVM server, and went to create a pool.
Running the 'test connection' that worked fine.
Trying to add the pool - failed. I got the error 'Cluster Not Available'
On the OVM server I did a repos.py -l and nothing gets listed.
I understand that for HA you need a repository with shared storage. However, before I have used these same install CDs with a singe local hard disk, to get OVM server running, and it did so fine.
So what's different with the USB disk install that means you don't get a repository?
Do I have to create a special repository LUN, manually connect the OVM server to this, and then use repos.py to create it?
Cheers,
Jeff

Ok I have read, re-read related parts of the underground manual and have hit a brick wall with the 'simple' task of setting up a NIC for dedicated iSCSI traffic. The manual does not cover this task in the iSCSI SAN section.
So I'm in a catch 22.
My OVM server boots up, with it's single management NIC configured, but once booted - I don't want to connect to the iSCSI target via this network - I need it completely closed off.
I want to use another NIC (or bond of two) for dedicated iSCSI traffic to and from the OVM Server.
However, the underground manual strangely only seems to cover a single NIC configuration! It looks like he assumes you are going to be running iSCSI on your management NIC, which I can only think is incredibly bad practice.
I have installed OVM with the linux asknetwork - this did not give me the option to configure additional interfaces.
I then manually edited /etc/sysconfig/network-scripts/ifcfg-eth1 on the OVMServer, restarted network, restarted the entire box - I can ping my new NIC / IP locally from within the OVM server, but I can not connect to the iSCSI target, nor can I ping the iSCSI NIC on the OVM server from the target.
This is such a simple thing to try to achieve - super frustrating...

OVM Server 2.1.2 does not prompt for Networking

OVM Server 2.1.2 does not prompt for a network setup (ie DHCP or static IPs).
- I tried re-installing this several times
This same machine works with native Enterprise Linux 5.2 x86-64 networking.
The motherboard has two onboard Realtek 8111C chips (10/100/1000 Mbit)
http://www.gigabyte.com.tw/Products/Motherboard/Products_Overview.aspx?ProductID=2842
Will setting up networking by hand work with OVM Server 2.1.2?

OK I finaly made my Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller to work.
First install an Ethernet card in your box that OVM supports. This to make the OVM installation run smoothly.
When OVM is up and running follow the steps in [Mini-HOWTO] RPMs needed to compile a kernel-module on / for VM Server to get a working environment to compile modules.
Now get the driver for the unsupported card from ftp://61.56.86.122/cn/nic/r8168-8.008.00.tar.bz2 .
Unpack the file by running;:
tar -jxvf r8168-8.008.00.tar.bz2
Now follow the steps in the included readme file to compile and install the driver.
After this I edited the file /etc/modules.conf and changed the line
alias eth0 xxx
to
alias eth0 r8168
I then turned of the machine and removed my temporary network card.
When booted I ran system-config-network to configure the network once more to the original values I entered when I installed.

Oracle VM 2.2 Nic bonding

Hi everybody,
I want to set NIC bonding on my VM 2.2 server. How does NIC bonding work? Also would I have to do any setup on my switch? Thank you to anyone who can help me understand.

Monitoring the OVM server 3.1.1

Hi Guys
What are you using to monitor the ovm server aspect of OVM?? i.e. monitoring the cpu, disks, NICs etc etc
Thanks
Aamar

I'm bumping this thread in the hopes of getting better ideas.
I have a tool that I can use to monitor DOMU's already (they're just like any other system). I'm looking for ways of monitoring the OVM server hardware itself.
I'm guessing installing monitoring software on DOM0 would be frowned up, particularly by our administrators who are trying to treat the OVM server as an appliance, rather than a system. The less on it, the better.
Is there a CLI or some other remote method of monitoring?
I'm also looking for ways to monitor the OVM manager software (general OVM health, pool health, etc). Perhaps the OVM CLI is useful for this?

GUIDE: Oracle VM VirtualBox and Oracle Linux NIC bonding

What is Linux network interface bonding? Simply put, the Linux system provides a kernel driver, which can create a logical network device (bond) using 2 or more Network Interface Controllers (NIC) to accomplish link-aggregation and adapter fault-tolerance. For more information, please see the Deployment Guide at https://linux.oracle.com/documentation/
The channel bonding interface supports several modes of operation. In a typical active-backup set up for fault-tolerance, the system performs MII-based health monitoring of the network interface slaves (eth0, eth1) and assigns them according to bond options and interface availability. In active-backup mode (mode 1), only the current active network device is seen externally.
Linux bonding for fault-tolerance under Oracle VM VirtualBox does not seem to function as advertised. Searching the Internet for more information shows that other people have tried to set up Linux bonding using various virtualization products, virtual host network adapter and bonding options, but without success.
It appears the management of Media Access Control addresses (MAC) interferes with internal routing methods between the host and the virtual machine guest. Using the modinfo bonding command (fig. 1) shows a listing of available parameters for the bonding kernel module. The fail_over_mac parameter addresses the Mac address issue in VirtualBox.
Fig.1
# modinfo bonding
filename:       /lib/modules/2.6.39-400.17.1.el6uek.x86_64
                /kernel/drivers/net/bonding/bonding.ko
parm:           fail_over_mac:For active-backup,
                do not set all slaves to the same MAC;
                0 for none (default), 1 for active, 2 for follow (charp)
Configuration Example
Virtualization Product: Oracle VM VirtualBox 4.2.10
VM Guest OS: Oracle Linux 6.4 (x64)
VM adapter settings: Bridged Adapter, Paravirtualized Network (virtio-net)
Adapter1 (eth0): 080027436617, en0, Ethernet 1
Adapter2 (eth1): 08002708F36A, en0, Ethernet 1
Note: If you wish to reset the network adapter names and MAC addresses used by the Oracle Linux guest system, erase the content of /etc/udev/rules.d/70-persistent-net.rules and restart the virtual machine.
1. Create or modify the following configuration files:
/etc/modprobe.d/bonding-eth0_eth1.conf
alias bond0 bonding
/etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
IPADDR=10.0.2.12
NETMASK=255.0.0.0
GATEWAY=10.0.0.138
DNS1=10.0.0.138
DNS2=8.8.8.8
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
BONDING_OPTS="mode=1 miimon=100 fail_over_mac=1"
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes

SLAVE=yes
USERCTL=no
/etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no
2. Restart the system or network services (root):
Fig. 2
# service network restart
Configuration Test
Enter the following commands as user root to verify proper operation of NIC bonding:
Fig. 3
# tail /var/log/messages
bond0: setting mode to active-backup (1).
bond0: Setting MII monitoring interval to 100.
bond0: Setting fail_over_mac to active (1).
bond0: Adding slave eth0.
bond0: making interface eth0 the new active one.
bond0: first active interface up!
bond0: enslaving eth0 as an active interface with an up link.
bond0: Adding slave eth1.
bond0: enslaving eth1 as a backup interface with an up link.

During the above test, the client network connection from host 10.0.0.1 (ssh) was maintained without any noticeable interruption. As it can be seen from the syslog and ifconfig command output, the bond0 interface was automatically assigned either the MAC address of eth0 or eth1 and the fail-over worked as advertised.
Good luck!

Lost connection between ovm-manager and ovm-server (ovm 3.1)

Hi,
I have a manager as a VM on my laptop and a physical server as an ovm-server. Everything is fine when i boot the server but after some time, the manager stop to show the information from the server. in the ovs-agent log file the following messages are repeated regulary
[2013-08-29 13:06:19 6160] DEBUG (notification:289) Trying to connect to manager.
[2013-08-29 13:06:20 6160] DEBUG (notification:291) Connected to manager.

[2013-08-29 13:06:34 6171] ERROR (notification:64) Unable to send notification: (111, 'Connection refused')
I did not reboot neither the server nor the manager. No IP change. Rebooting the manager has no effect.
The only way to restore communication is to restart the ovs-agent on the server, but this restart disable the network card. I must be physical on the server to restart the network.
any help will be very helpful
best regards
Jean-Marc

Hi,
The are many steps to verify:
Verify with your firewall on the Oracle VM Manager system (service iptables stop).
Verify with a ping between OVM Manager and OVM Server using the IP Address and using the hostname for each one (from OVM Manager : ping ovm-server ; and from OVM Server: ping ovm-manager).
I hope this can help you
Best Regards

How to configure local disk on OVM Server as storage space to create VMs

Hello,
We have installed OVM Server 3.1.1 on a machine that has 250 GB of Hard disk space [Single disk].
While installing used an option - Remove all partitions and create a new default partition layout.
Around 4GB has been used and remaining 246 GB is left as free space.
From OVM Manager - the server is discovered but didn't discovered the physical disk [i.e. remaining 246 GB raw disk space].
Can someone help me to understand how to use local disk as storage space for creating and running VM's.
Thanks
Srinivas

You can? You've used every conceivable BIOS out there? You must really be full of yourself. There is absolutely no BIOS that I know of that gives this basic function. BIOSs do not "hard partition" anything. A "BIOS" is not made for such things. Do you even know what "BIOS" stands for?
I wonder why there is some many wanting to do this and are having problems.... I mean if it is such a straight forward thing to do..... It must be down right "intuitive".
You maybe speaking of a RAID "BIOS" but you obviously think you're not. Some motherboards have integrated RAID abilities. Intel RST comes to mind... BUT this isn't a feature of a MOTHERBOARD BIOS.
I've got some $50,000 servers that will not break a single hard drive up into multiple logical drives..... Now, I haven't worked on a "Stinkpad" for many years. Don't want to. However, I have never seen one that would do what you're saying you're doing.
You maybe trying to help.... but you're leading people down a wrong path.
Its just as easy to run virtual box and use the virtual box templates for Oracle VM. In fact, its more practical if you want to run Oracle VM on a laptop for testing purposes than blowing everything away and attempting to setup different LUNS on a single hard drive.
For your review...
http://www.oracle.com/technetwork/articles/servers-storage-admin/configure-vm-templates-1656261.html
Although it's more reliable to use a separate location (such as an NFS share) for a storage repository, you can use a local disk of your Oracle VM Server instead, thus taking advantage of the local storage option. Beware, though: Oracle VM Server 3.0 doesn't allow you to utilize the unused space on the physical disk it's installed on. For local storage, you'll need at least one more physical disk. In other words, you'll need a total of two disks at minimum on your Oracle VM Server host if you want to use local storage. In practice, though, local storage is not a primary use case. The major downside to this approach is that local storage, by definition, cannot be shared between different servers.

NIC Bonding not behaving as it should

Hi Folks, am trying to setup NIC bonding on my VM (OEL5u6) having two virtualised NICs, i have done the setup which is quite simple however my active-backup mode is not working as expected.

I am doing a continous ping from another host in the same n/w to this bonded interface IP to check if the ping streak breaks when i test this setup
Testing -
[root@Gateway network-scripts]# ifenslave -c bond0 eth4
and that's it my SSH connection is gone, and ping is broken with "Request timed out"
when i check the bond status now -

am afraid there's not much help in the message log to debug this.
Any views what's wrong and how to resolve? appreciate ur replies. Thanks

CSACS-3415 ACS 5.4 NIC Bonding / Teaming possible ?

Hi Team,
I know, this topic has been answered for the "old" 11x Appliances: not possible.
Does the new UCS hardware change anything ?
Can we bundle 2 NICs somehow to get interface redundancy ?
If still not possible to configure that in ACS 5 itself:
Can it enentually be done on the "hardware" level
within the appliance firmware (UCS BIOS) ?
Frank
(RHEL would provide NIC bonding,,, unfortunately its not accessable from ACS5 CLI)

Yes it does. ACS 5.5 with the Cisco SNS-3415, Cisco SNS-3495, virtual machine, or CSACS-1121 platform allows you to use up to four network interfaces: Ethernet 0, Ethernet 1, Ethernet 2, and Ethernet 3.

OVM Server 3.2.1 install reboots server

I have been trying to install OVM Server on an IBM xSeries 336 server. OVM Server 2.2.1 was previously installed on this server.
Trying to install 3.2.1 now and I get to the splash screen booting from the CD. I press [Enter] to begin the installation. Once the process reaches the point of 'Loading SCSI driver', the server reboots. I have tested the media on other machines without issue. I have also tested the server with OVM Server 2.2.1 media and the install progresses normally to the end.
I suspect there are missing drivers causing the install to fail. Is there a way to load the missing drivers during the install process?
Thanks in advance,
UPDATE: I have successfully installed OVM Server 3.0.2... Not exactly what I wanted but....

Oracle VM 3 is entirely different from 2.2.1.
take a look at the release notes for 3.2.1 There are few instances in which you have to specify different boot parameters for the installation to work.
http://docs.oracle.com/cd/E35328_01/E35329/E35329.pdf
You might have a MEGARAID product.
If you are installing Oracle VM Server on a Sun Fire X4800, you must provide extra parameters when
booting from the installation media (CDROM or ISO file), or when using a kickstart installation. These
parameters allow the megaraid_sas driver to load correctly.
If booting from the installation media, press F2 when the initial boot screen is displayed and provide the
following additional parameters as part of the boot command:
mboot.c32 xen.gz extra_guest_irqs=64,2048 nr_irqs=2048 --- vmlinuz --- initrd.img
If using a kickstart installation, add the additional kernel parameters to the PXE configuration file.

Problem with OVM Server 3.2.6 - xend not running

Hi, just now I upgraded my server to OVM Server 3.2.6 version and server boots up, cluster is up but I have message that Hypervisor is running in UNDETERMINED bit mode (WARNING: XEND IS PROBABLY NOT RUNNING). While boot I saw message that xend failed to start because "mount point /proc/xen does not exist". Also when it tries to start xend, there is message "xencommons should be started first". Reinstalling OVMS did not help. Does anyone have this problem?
Thanks.

For me, it looks like the same.
1 - Yes
2 - B
3 - Not yet, I've tried to downgrade to 3.2.4, but it is not possible.

Install OVM server 3.2.1 on iSCSI LUN

Hello friends,
I have a Cisco Blade and would like to boot OVM server from an iSCSI lun. I create a LUN from a SAN and presented the lun to the blade. When the server boots up, it sees the iSCSI lun just fine but when I tried to install OVM server 3.2.1, it did not detect that LUN. I tried to install Oracle Linux 6.3 and it sees the LUN ok. Is there a way to make OVM server to see that LUN.
thanks,
TD

I have done to many oel and ovs install lately such that they are blurring together...
On the OVM 3.2.1 install watch closely for a place to add support for non local storage. I remember seeing a small prompt in some of the installs but it may have been from some of the OEL installs (I have also been doing OEL 4, 5, & 6) & not OVM.
Sorry I can't remember right now. If I get a moment and try to run the install process I will and report back if no one else does.

OVM Server 3.1.1 errors

I am running OVM 3.1.1 in a 2 servers cluster. on one of the server I noticed that following errors happening very frequently in /var/log/ovs-agent.log. whereas 2nd OVM Server has no errors. I also noticed in OVM manager that if I go to "repository" tab, every thing in repository has "lock" sign on it.
I am trying to create a clone from one of the templates but it just stays in "in progress" at 0% for ages and nothing happens.
I do not have any idea where and why these errors are generated. Any help would be much appreciated.
Thanks

Did you get any resolution to this problem?
I'm getting the same errors and I can't find anything on MOS which indicates what could it be. Same setup as yours, 2 servers in the cluster pool and one is throwing errors and the other is not.
