Oracle VM guest NIC vendor

Hi everybody,
Is there a way to change the type of NIC that a guest VM will use? I have Oracle VM 2.2 setup and running fine, all my guest VMs use a REALTEK-8139C+ NIC. Is there way have my guess VM use another virtual NIC? I hope this makes sense. Thanks.

I strongly recommend using PV drivers in all your guests for performance reasons. The only time you'll see an emulated NIC is in HVM mode with no PV drivers. In that case, you can change the model= parameter in vm.cfg to either e100 or e1000 as described in the [C.1 e100 And e1000 Network Device Emulators|http://download.oracle.com/docs/cd/E15458_01/doc.22/e15444/templates.htm#BABEDEIF] section in the manual.

Purpose of 2nd guest NIC (10.10.10.21)?

Why are both guest NICs connected to NAT/vmnet1 (192.168.203.0/24)?
Although the 2nd guest NIC (eth1) is set to 10.10.10.21, it is connected to NAT/vmnet1 (192.168.203.0/24), not host-only /vmnet8 (10.10.10.0/24).
This was from a clean and completely default installation of the 2/10/2005 disk set on a WinXP host.

In my original post, I should have written vmnet1 for vmnet8 and vice-versa; otherwise, it is correct, and is consistent with what I've written here.
I made a virginal install using the default install options of the 2/10/2005 disk set Oracle Installer version of VMware Workstation 4.5.2 w/SLES9 on a fresh WinXP Pro SP2.
The Oracle Installer installed VMWare as follows (from screenshot of "Virtual Network Editor", "Summary" tab):
VMnet0 (Bridged)
VMnet1 (Host-only) 10.10.10.0
VMnet8 (NAT) 192.168.203.0
There is no 2nd NAT configured.
The Oracle Installer installed the guest machine (SLES9) as follows:
NIC1 is connected to NAT
NIC2 is connected to NAT
Hence, both NICs are connected to the same vmnet (VMnet8).
Within the guest machine, "ifconfig -a" reveals that
eth0 (NIC1) has address 192.168.203.21
eth1 (NIC2) has address 10.10.10.21
(Also virtual interface eth0:1 has 192.168.203.121)
eth1, however, has an IP address consistent with VMnet1, although it is attached to VMnet8.
In a cmd window on the host, running 'ping 192.168.203.21', 'ping 192.168.203.121' receive responses, but 'ping 10.10.10.21' does not.
If I interpret Saar's comments correctly, the network is misconfigured as installed. NIC2 should be attached to VMnet1, and VMnet1 should be changed to NAT from Host-only.
After moving NIC2 to VMnet1 (Host-only), all three of
'ping 192.168.203.21', 'ping 192.168.203.121', 'ping 10.10.10.21' receive responses.

Hyper-V guest NICs fail

So I got two new servers a Dell R620 and a R720 running Hyper-V on Windows 2012 R2 all clients on them are 2012 or 2012 R2.
All NICs are Broadcom NetXtreme, 2 quad port per server, I am currently running 15.6.0.10 drivers with 7.6.15 firmware on the R720 and 16.2.0.4 drivers and 7.8.16 firmware on the R620. No guest NICs are teamed.
In the last 2 weeks I had two guest NICs in hyper-v (with a few days between) on the R620 and 1 on the R720 fail to a point where the NIC cant communicate with the network, getting a 169.x.x.x IP address. I delete the NIC in the Virtual Switch Manager, re-add
it and everything is fine again. I don't allow the managing OS to share the network adapter, for the most part, I use 1 NIC per VM.
I recall this happening back with Hyper-V 2008 R2 as well, but generally at the time of a driver update or some sort of change. These Hyper-V hosts have no received any drivers, firmware or Microsoft updates anywhere around the time of these failures.
Any ideas?

Hi,
" In the last 2 weeks I had two guest NICs in hyper-v (with a few days between) on the R620 and 1 on the R720 fail to a point where the NIC cant communicate with the network, getting a 169.x.x.x IP address. "
It seems that there is a DHCP server in your LAN.
I would recommend you to do :
1. check if there is any new driver for your NICs
2. check whether mac address conflict exists .
3. disable the "save power " mode of your NIC

Oracle VM Guest Templates

Today i installed a server. The download of the guest-template worked fine, installation done within minutes as described in the manual.
two questions:
1) i configured the vm.cfg file for use with vnc (vnc=1, vncconsole, vnclisten....) and read in the manual that with vncunused=1 always another port is taken for vnc-access.
How can i realize to get always the same port for the same guest? Currently always 5900 is taken for the first guest-start, is okay for now, but when i have more than 1 guest it would be fine they always have the same vnc-port.
my config-parameters are:
vnc=1
vncconsole = 1
vnclisten = '0.0.0.0'
vncunused=1
2) whats the root-pw of the VM Guest Templates, did i read over this essential info?
my guest is now up and running, but i can't login.... :-(

Thanks a lot!
Can you tell me where you got the info from, which manuals would be fine to get a little more information on that?
P.S.
I also got an information from Oracle they will include the password in the README file in the future

Oracle vm guest disk count limitation

Hello!
Recently I've deployed oracle virtual server (3.2.2), and have a task for virtual machine creation with solaris 10 x86 installed and 5+ physical disks attached to the system from various SAN storages. Xen HVM domain type has a limitation of 4 disks attachable, so I've changed domain type for Xen HVM, PV drivers on the cloned machine, but I'm unable to apply 5 disks attached configuration to this vm with following error:

Oracle VM Guest Performance as HVM

All,
I was hoping to get clarification on this:
I happen to have a server with a processor that supports virtual machine in hardware (AMD-V). I have installed a couple of 64-bit OEL5u4 VMs off of the install iso (not from eDelivery templates, but from eDelivery iso). My guess is that these guests think they are using the hardware directly, which, as I undertand gets to be finally handled by qemu-dm in Dom0. Is this an efficient way of doing things with these OEL versions, or should I consider altering the guests so that they can communicate with Dom0 in a more efficient manner? The Oracle web site offers rpms for the guests, but seem to be targetted at OEL5 Update 1. Maybe these improvements are built in OELu4?
FWIW, I ran "hdparm -tT /dev/sda" on the host, and "hdparm -tT /dev/hda" in the guest, and the buffered read performance is worse in the VM by a factor of 5. The way I configured it, hda in the guest maps to a Logical Volume block device on the host, so I was hoping to get much better performance.
Any input welcome.

FWIW, I pursued this by reading the Oracle Server manual again, as well as what I could find from RHEL5. Again, this is trying to configure a guest with paravirtual drivers when the guest is run in full hardware virtualization, in order to retain as much disk performance as possible.
The short of it is that if the vm.vfg file makes use of "xvda" instead of "hda", then OEL5.4 uses the disk in a much more efficient manner (meaning it does a hypercall from DomU to Dom0, so Dum0 stops using the slower emulation in Dom0).
In my case, I chose to map the DomU hard disk to a Logical Volume in Dom0:
disk = [
'phy:/dev/DomUDisk2/LVOracleApp,xvda,w',
In this case, running "hdparm -tT :/dev/DomUDisk2/LVOracleApp" in Dom0 yields to near identical results to running "hdparm -tT /dec/xvda" in DomU. I used to have a loss of a factor 5 with emulation.
If anybody has to retrace my steps and try to replicate this, there are guides out there that mention installing missing paravirtual driver modules in the guest by downloading some rpm. Starting at OEL5.4, they are already there (/lib/modules/2.6.18-164.el5/kernel/drivers/xenpv_hvm/), so no extra rpms are required.
There is one caveat: Booting from xvda using the paravirtual drivers is somewhat less than automatic. Contrary to what you can read, grub does not seem to have a problem locating the kernel and initial ram disk. So, after grub does its thing and gives control to the kernel, the init script in the ram disk tries and locate the root file system. It then scans and finds the hard disk as hda (emulation), eventually mounts it, and runs init off of the disk. This new init has the paravirtual drivers from the hard disk, and finds the SAME DISK as xvda. This cannot be good, although it works and does not seem to thrash the file system as one would think. In order to prevent this from happening, there are a couple of changes to do in the grub configuration file /boot/grub/grub.cfg). The idea is to prevent the kernel from scanning for IDE disks:
kernel /vmlinuz-2.6.18-164.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet hda=noprobe ide0=noprobe
Now, once this is done, we have prevented the kernel from finding the root file system, and this VM is unbootable! The problem is that the initial ram drive does not have the paravirtual drivers built-in, so xvda, with the root file system, cannot be found. Fortunately, adding the paravirtual drivers to the initial ram drive is undramatic:
mkinitrd -f newinitrd 2.6.18-164.el5 --omit-scsi-modules with=xen-vbd with=xen-vnif preload xen-vbd preload xen-vnif*
The newinitrd file can then be copied to /boot with the right name for grub.
I thought I would pass this along as I found that there were great benefits to running the DomUs this way, performance-wise. At this point, I am not sure how these configurations would survive an upgrade of the kernel. I would think that an update to the initrd config file is in order. Thoughts welcome.

Oracle VM guests and CPU Licensing ?

Hello All,
1. If i have a server with dual core (means 2 cpu's in a single chip isn't it?), when it comes to Oracle DB licensing based on CPU.
Do i need to count them as CPU= 2 or CPU=1 ?
2. Will i get better performance if i set Virtual CPU=4 for guest OS despite having only a single physical CPU in the machine ?
TIA,
J J

Nope. :) Your 16 core license covers all 16 cores in the physical server, so you can run as many Oracle DB instances as you like. You can even over-commit VCPUs, i.e. give each guest 4 VCPUs for a total of 32 VCPUs on a 16-core machine. This still doesn't require any more licenses.
This is only recommended if your databases would only really use 20-40% of physical CPU cycles. If your instances are going to be quite busy, I wouldn't recommend over-committing.

Oracle Vm guest boot order

Hi,
is there any possibility to setup VM guest boot order in Oracle Vm server. For example i have VMs 1,2,3 and when the Oracle Vm server is restarted, i want the VM guests to boot automatically in the following order:
VM2(database)
VM3(Forms & reports)
VM1(BI pubisher).
regards,
Savo

Hi there Savo,
the only approach I am aware of is to create symbolic links in
/etc/xen/auto to point to the respective guests' cfg file. Though you
can play around with naming the links to accomplish proper boot order,
you still may experience issues as the hypervisor will start the
machines but the individual time for loading OS and other software may
vary. Based on this you may have one machine started before another, but
the second to start all services faster than the first one. Hence,
having issues.
Take a look at this threa <https://community.oracle.com/thread/2446485>d
and pay attention to the last post as I have not tried it.
In general both approaches will impose a great level of inflexibility in
a clustered pool as you have to carefully plan where each machine will
start after dom0 reboots.
Hope this helps,
Anatoli

GUIDE: Oracle VM VirtualBox and Oracle Linux NIC bonding

Author: Dude

Last updates:

The following is provided in the hope that it might be useful. If you wish to use it for the purpose of reference, presentation or education, please include the link or information to this forum posting. Thank you!
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
MASTER=bond0
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).

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!

Installing 11gR2 (linux.zseries64) on oracle linux 5 guest system failed

Dear experts,
I decided to post a detailed thread since it seems my last thread is totally forgotten. Hopefully, this thread could clarify my problem of installing oracle database 11.2.0.2 in oracle linux guest system in windows 7 host system. Sorry about that.
I installed oracle linux 5 update 6 x86_64 bits guest system in my windows 7 host using oracle virtualbox 4.2.12 so that I can install oracle database 11.2.0.2 (linux.zseries64_11gR2_database_1of2.zip, linux.zseries64_11gR2_database_2of2.zip). The oracle database I downloaded has some functions which are not available in 11.2.0.1. These two disks are extracted in a shared folder.
I followed the instructions in a guide to run the installation:
# yum install oracle-validated
It succeeded. and, I used uname -a to return this additional information:
"Linux localhost.localdomain 2.6.32-400.26.2.el5uek #1"
Then I set these below:
SELINUX=permissive
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01
xhost + 127.0.0.1
and, added something in .bash_profile:
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_HOSTNAME=127.0.0.1; export ORACLE_HOSTNAME
ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
ORACLE_SID=DB11G; export ORACLE_SID
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
Then, I set DISPLAY environment in terminal:
export DISPLAY=127.0.0.1:0.0
Finally, I logged into the guest system as a user, not root, to run the installation. However, I got the frustrating error message:
[hsl@localhost database]$ ./runInstaller
./runInstaller: line 254: /media/sf_My_Share/Oracle/database/install/.oui: cannot execute binary file
Can anybody please give some advices to fix the problem. The installation is very important to me. Thanks a lot in advance.

NIC teaming in OVM

Hi folks,
Does Oracle VM support NIC Teaming(Bonding of more than 1 NICs in to 1 Logical NIC)? Does it require any driver or patch for the same.
I have SUN server x4710 which has 2 NIC cards.
Moreover If I ve VMs(guests) with IPs of different VLANs(Eg. 10.22.70.x and 202.49.214.x) residing on same VM server what would be the best practice?
Hope fully I have made the points clear..
Thanks in advance...

Moreover If I ve VMs(guests) with IPs of different VLANs(Eg. 10.22.70.x and 202.49.214.x) residing on same VM server what would be the best practice?I usually create a bridge per VLAN. That way, I can create a virtual interface to a guest that is already on a particular VLAN and the guest doesn't have to worry about VLANs. Also, it means you can control VLAN assignments outside the guest OS. See this wiki page for more info:

LXC guest cannot receive any packets

I am using vagrant-lxc, and it was working for a while, but one day it stop working. I tried using netctl for a while, but I switched the libvirt in the hopes of getting it working again, and it did... until I restarted
Here is the situation now.

I tested that packets can get out using netcat to send UDP messages, and I received the messages on a server on the WAN, so I know packets are getting out, but they are not making it back.
I've tried removing lines 4 and 5 from the FORWARD chain, but it didn't help.

I had some weird issues with two Windows Server 2k8 R1 guests and networking between the two experiencing difficulties after some random amount of time. A reboot often fixes it for a short period of time, but then it comes back.
After a thorough investigation with Oracle Support, we didn't identify the root cause; however upgrading to Oracle VM 2.2.2 fixed the issue.
Edit: To clarify, my issues were that RDP and mapping network shares between the two servers wouldn't work... but communication to other non-OracleVM (and some Oracle VM guests as well actually) was fine.
Doing tcpdump traces on dom0 identified intermittent packet drops somewhere between the xenbrXX interface and the underlying network interface (e.g. in my case, bond0.XX).
