Virt-manager (libvirt) set up bridged network

I have googled and searched and can't find instructions on setting up a bridged network for use with virt-manager. The instructions at
https://wiki.archlinux.org/index.php/KV … Networking
don't really seem to apply to starting vm's with virt-manager. Does anyone have experience setting up a bridged network with libvirt on arch?

In case anyone stumbles upon this in the future (as I have done):
Setting this up with virt-manager is pretty simple.
First, you need to create a bridge. You can do this manually or use most of the network management tools for this. I used systemd-networkd (just ignore the stuff about the container). You could also use netctl ore others.
After you created the bridge and added your default network device to it, open the network device of you vm (or create one if there is none) and switch the "Network source" to the bridge you just created. And with that you should be fine.
PS: I just saw that virt-manager seems to be capable of creating bridges by itself, right-click you hypervisor, go to "Details", "Network Interfaces" and create a new bridge.

Cannot find Airport after attempting to set up Bridged Network

I had a previous post on creating a bridge network (with two base stations - one plugged into a modem "A" and one plugged into my Mac Pro with an ethernet cable "B". After doing the following, the bridge does not work - and more importantly - I cannot find base station "B" with the airport Utility at all.
I did the following:
Set up base station "A" to "Share a Public IP Address"
Set up base station "A" to "Allow this network to be extended"
Updated settings on "A" (allowed it to reset)
Set base station "B" to Bridge Mode
Set up base station "B" to connect to the wireless network on "A" (with the same password and configuration (WPA2 Personal)
Configured the TCP/IP on "B" to be the same as on "A"
Updated settings on "B"
I did this initially and it did not work - on "B" there was an error concerning "Network Extended" and it said the airport was having problems extending the network (which is in the next room, I don't know how that is possible). Anyway the bigger problem is after updating "B" again, it is not recognized by the airport utility at all - not by my macbook pro (which was seeing it before with the wireless network) or the Mac Pro that is plugged into it with an ethernet cable (I've double checked that it is one of the "out" ports, not the input for the airport). I have also plugged it into my macbook pro with an ethernet cable and get the same problem. It is just delivering a flashing amber light. I have unplugged it and plugged it in again, reset all of my computers, but nothing I do allows me to connect to Airport "B" to use the utility. Any ideas?

The thing I am not seeing in your posting is that each of these devices has a similar but not identical IP Address.
Are you using DHCP to assign addresses? Which Router is assigning them, what range are you using? If assigning by hand, are they all similar, but not identical? It may help to list them.

Bridge Network Adapters Always Start Disconnected

I've been working on this for two weeks with no success. Everytime I reboot my server, Windows Server 2008 R2 & VmWare Sever 2.02 any VMs that are set to bridged networking boot with their network adapter set as disconnected. It requires a manual "click" of the checkbox to turn on the network adapter. I have been using VMware server since version 1 and have never had this problem. One unusual thing is the Manager Virtual Networks Auto-Bridging doesn't seem to show any network adapters, although networking continues to work. If I set my VM to NAT or host only my adapter starts connected, as it should.
Things I have tried:
Uninstall VmWare server & Reinstall
Uninstall and create various VM Hosts, all do the same, pre-compiled applicanece and all costum built.
Moved host images to another server (works fine)
Checked to make sure Bridge Protcal is installed on ethernet adapter, even removed and readded.
Uninstalled and reinstalled ethernet adapter (Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller(NDIS6.20)
This is a Windows Server 2008 R2 box with lots of ram and plenty of resources only running spiceworks & splunk in a test capacity. Using this machine for testing and pre-deployment but it's virtual machines need to act like they would in production.
Any help would be greatly appreciated.
Thanks

Opps typo, I moved the VM images to different hosts, Windows server 2003, 2008 and 2008 R2. My home box runs 2008 R2 and Vmware server nicely together without this issue. Hence why I'm at a loss.
Thanks for your interest.

[SOLVED] KVM and Bridged Networking

I've got KVM working and a Windows 2008 server installed on a image now, but it's only getting a NAT ip address. I need to get this server onto my main network, on Windows I'd use Virtual Box and Bridged Networking, but I thought I'd give KVM a try out.
I've followed the setup at https://wiki.archlinux.org/index.php/KV … Networking
Using Netcfg
Bridged networking is used when you want your VM to be on the same network as your host machine. This will allow it to get a static or DHCP IP address on your network, and then you can access it using that IP address from anywhere on your LAN. The preferred method for setting up bridged networking for KVM is to use the netcfg package. You will also need to install bridge-utils.
Netcfg#Configuring_a_bridge_for_use_with_virtual_machines_.28VMs.29
And this page https://wiki.archlinux.org/index.php/Ne … _.28VMs.29
I've got a bridge working I believe (all my stuff is DHCP by the way)

I've got "bridge" added to my rc.conf as a MODULE which is loaded. (I saw reference to this somewhere else on the forum that this might be needed)
I'm starting my VM with the following command
qemu-kvm -vnc 192.168.1.52:0 -hda Nekomi -m 2048 -smp 2 -net nic
Yet I still can't get an IP outside of the 10.0.0.0 range on the VM.
The VNC line above is because the HOST has not VGA output at all, completely headless.
I'm trying to get this working and trying to learn at the same time. KVM is new to me, as is bridged networking on linux.
Any ideas? Thanks

Sorry for the delay, bit a PC rebuild occurred :-(
Anyway, I managed to get this working with steps #1-#7 from the linked section. Thanks for that. I did have a few minor issues in getting a DHCP on the host machine itself, turns out I'd missed a single ) from the daemons section of rc.conf. A human error, but difficult to fix as the machine was rendered off the network and without a VGA card... fun!
I diverge, I have this script to bring up a bridge when the qemu-kvm starts
#!/bin/sh
echo "Executing /etc/qemu-ifup"
echo "Bringing up $1 for bridged mode..."
sudo /sbin/ifconfig $1 0.0.0.0 promisc up
echo "Adding $1 to br0..."
sudo /usr/sbin/brctl addif br0 $1
sleep 2
But when the kvm shutdowns it complains it can't find qemu-ifdown script. So I'm thinking of making one but just want to check it over first.
#!/bin/sh
echo "Executing /etc/qemu-ifdown"
echo "Removing $1 from br0..."
sudo /usr/sbin/brctl delif br0 $1
echo "Taking down $1 from bridged mode..."
sudo /sbin/ifconfig $1 0.0.0.0 promisc down
sleep 2
I've reversed the logic here, is the above the correct way to bring down the guest interface?

I'm having the same issue. Not running Windows though... I have a minimal Ubuntu 14.04 as the guest (Arch as the host.) Been trying everything I can think of but I can't get any sound in virt-manager. Like you said, the sound seems to play OK in the guest, it's recognizing the card, volume is turned up but no sound. It has to be an issue with my host configuration but I'm not sure what. I can get sound to play in the same guest if I launch qemu directly and use ac97. Something's gotta just be misconfigured with virt-manager/libvirt/Spice. I thought a permissions issue at first since by default it runs as the "nobody" user but I even tried the foolish thing of setting /etc/libvirt/qemu.conf so qemu runs as root... still no go. I'd really like to use virt-manager for the nice GUI, presistant settings, and extra features like Spice and the QXL driver that enables KMS on the guest.

HT201334 How does one set up profile manager on a completely closed network with no Internet access available or even possible?

I need to set up Profile Manager on a completely closed network that has no Internet access at all. I can sneaker-net files into the network if I need to.
Profile Manager (and Lion Server in general) seems to need outside access to complete setup and I've been unable to find any meaningful answers.
Does anyone any any ideas?
Thanks to all

you could try it without enabling apple push notifications in server
you wont' be able to push out profiles without enabling apple push notification
but users could download them, or you could install manually, e-mail etc

Setting up Bridge for multiple users on a network

New Bridge user here
Can anyone give me some advice on how to set up Bridge for use by multiple users over a network / server?
We have a large image bank stored on a server and ideally if any one user adds keywords or other metadata to an image I would like the rest of the users to be able to view that data and be able to use it in searches. AS more than one user could add keywords at any time I was wondering is it possible to set up a central keyword file or cache so any updates are available to all users.
Do I set up a shared cache? What happens if it becomes corrupted and has to be rebuilt, do the keywords disappear as well?
Are the keywords associated with that particular cache or are they stored in a separate file?
Thanks,
Hazel

Curt
how do you know if your using the
Central cache all distributed cache ?
and are they both stored in the same place ?

Deleted Colour Setting in Bridge, but Photoshop wants to Colour Manage every time I open a file.

I installed a Colour Setting in Bridge as per a printer's instructions. After I did this, every time I open something in Ps, It asks if it can colour manage the file and gives a few options. I deleted a Creative Suite Colour Setting from finder Bridge, but Photoshop still generates the popup every time. This interferes with Scripts in Ps and it's very annoying.

Deleting something in Bridge certainly won't help.
Change the color settings in Photoshop...

Setting up bridge as photo database for a small company

My company is using a quite large collection of stock photos. Those photos are currently saved in appropiately named folders, however it's quite hard to find a specific type of photo this way. That's why we want to start using bridge for the management of our stock photos.
I searched the internet for tips on how to do it, however most of the threads are really old (we are using CS 5.1) or not very helpful.
That's why I hope the adobe community can give me some advice on how to set up bridge for a small company network (~20 people).
What we want to achieve:
Bridge uses the stock photo folder located on our server
All photos have tags, if someone changes a tag the other users also see the changed tag
If a new photo is added to the server, it shows up in the bridge of all users
Not everyone in the company is using macs -> everything should work cross-platform, also for the windows users
Not essential but would be pretty helpful: Since 90% of our photos are from iStock, a way to read the tags from iStock and insert them into our photos.
I know that there are other programs which are better suited for the management of photos, however we want to rely on an Adobe product for it and since Lightroom does not seem to be a good choice, we look forward to using Bridge.
Maybe someone else in here also uses bridge for the photo management in their company or knows how to set it up for a network. If so, I would be very grateful for an answer!

Maybe the command line shows some errors.Try something like
/usr/bin/kvm -M pc -monitor pty -boot d -hda /dev/vg01/opsi -cdrom /root/debian-500-i386-netinst.iso -net nic,macaddr=00:16:3e:49:da:10,vlan=0 -net tap,script=,vlan=0,ifname=vnet0 -serial pty -parallel none -usb -vnc :0
-hda is where you want to install the machine. Here it's a logical volume, but you can also use an image.
-cdrom is the installation medium
you can probably omit -vnc :0. I used it because I install machines on servers without gui.

Best way to set up home network with NAS

I'm pretty novice with networking, but do have some knowledge and know what I am trying to accomplish, but the two just aren't clicking.
Here's what I'd like to do: Have a storage central to our home office, which consists of two iMacs, a MacBook Pro, iPad, two wireless printers, two iPhones. I just purchased a 6TB Lacie 2big NAS and the 6th gen AirPort Extreme. Currently, I am able to access the storage wirelessly just fine, which is great, but I am working with large files (10gb-60gb) and needing to move them a little quicker. Most of the time, these files are being dumped onto the one iMac by way of Compact Flash cards via a highspeed card reader. I need to be able to access those files from (most importantly) the iMacs and (not so importantly) the MBP, which again, I can right now, but the transfer from CF card to iMac to NAS takes way too long wirelessly. So, what are my options? Do I get two more gigabit Ethernet cables and run them from the iMacs directly into the other two ports on the AirPort Extreme or should I purchase a separate gigabit switch then connect that with NAS and two iMacs or is there another option that will give me optimal transfer speeds from either iMac (including external HD's attached to the iMacs) to the NAS?
Thank you so much in advance.

should I have the base station set to run bridge vs route or does that not affecting anything?
If you have the AirPort base station set to "bridge", then the signal will pass through the AirPort and on to your modem/router which will do the actual "routing".
That's OK, as long as the modem/router also has 1,000 Mbps Gigabit Ethernet ports.
However.....if the modem/router has slower 10/100 Mpbs ports, the Gigabit signal will slow down by a factor of 10 passing through your router, and file transfers will be much, much slower, as you can imagine.
Another way of saying the same thing is that to get faster Gigabit speeds, everything has to be Gigabit capable.
Unfortunately, Bridge Mode is the correct network setting for the AirPort Extreme if you have a modem/router "upstream" on the network. Then you may get caught in a Catch 22 situation.
if I opt to use a switch (so I can add another 2big NAS), will that result in slower sports vs going straight through the AirPort Extreme
No, speed will not be affected either way, since it makes no difference how things are set up....so choose the setup that is easiest to implement.
In other words, if it is easier to run a single Ethernet cable from the AirPort Extreme to the Gigabit switch and plug other devices into the switch, then that is the way to go. The performance will be the same as if you had run two separate Ethernet cables to the AirPort Extreme.

Trying to set up wireless network on PC with Airport Express

I'm helping a friend set up his network with AirPort Express. He's got a modem attached to his PC, and currently has a router that sends a wireless signal to a receiver on the PC in the other room. Now he's added a Mac, and the old router/receiver doesn't work with Mac. So he bought an Airport Express.
I've turned on the Airport, and first I connected the ethernet cable from the modem to the AirPort. Per the AirPort utility I put on the PC, it couldn't find it (got the flashing amber light). So then I took out that ethernet, and I hooked up the ethernet directly from the CPU to the AirPort. Suddenly, it was found, and it took me step by step through the set up. It asked for password info from our internet provider (??why would I have that info??), so we just hit "enter". Then it couldn't set up the network, and said to check the "manage network settings". I've tried everything. Not only can I NOT manage to create a network, but now NEITHER ethernet cable will cause any recognition in the AirPort. All I get is the blinking amber light. I'm about to throw all the computers out the window...it really should not be this difficult. I've set up networks in my own home, before, with both PC and Mac, and never had these problems. So, now, I've had to relink up the old router/receiver in order to send out this call for help. Can anyone suggest anything else to try before I use these computers for target practice?
Thanks in advance,
Jennifer
P.S. The main PC w/modem is on Vista with service pack 2.0...since I can't even get that one working with AirPort, I hardly think it matters what the other computers are...

I had some initial problems too. Make sure that you have the latest Airport Utility in the utilities folder. I used that to correct the problems I had when I first got Time Machine. I recommend resetting everything through there to get it working right.
Mine is not set up to run an n network because my macs are all g and b compatible. Does the airport utility see the time machine? And if so, does it have a green light in the utility?
