USB redirection under CentOS 6.4
by carlopmart 04 Oct '13

04 Oct '13

Hi all, Does usb redirection works?? I am trying to assign to a Win7 kvm guest an usb HP printer without luck ... My second attempt is to use usb redirection, but according to Redhat's docs, this option is only available for windows using RHEV ... Is this correct?? Exists another tool to assign a printer via usb to a kvm guest?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

Solution was relatively easy and mainly a matter of understanding the "ifcfg-eth0 - like" files. What I did: 1 - yum install bridge-utils 2 - change /etc/sysconfig/network-scripts/ifcfg-eth0 to: DEVICE="eth0" BOOTPROTO=none ONBOOT="yes" TYPE="Ethernet" HWADDR=xx:xx:xx:xx:xx:xx BRIDGE="br0" USERCTL=no IPV6INIT=no NM_CONTROLLED="no" 3 - change change /etc/sysconfig/network-scripts/ifcfg-br0 to: DEVICE="br0" BOOTPROTO=none ONBOOT="yes" IPADDR=192.168.0.95 NETMASK=255.255.255.0 GATEWAY=192.168.0.1 DNS1="192.168.0.1" PEERDNS="yes" TYPE="Bridge" DELAY=0 STP=off USERCTL=no IPV6INIT=no NM_CONTROLLED=no 4 - /etc/init.d/network restart 5 - choose Host device eth0 (Bridge 'br0') in the VM-manager GUI for the virtual-machine's NIC 6 - restart the virtual machines That made it all work. So what I had wrong initially were settings in the ifcfg-xxx files. There are different settings that may work and I just tried some of the not-working combinations. Cheers, Koos.

moving the Xen4CentOS repo Kernel to 3.10.x
by Johnny Hughes 25 Sep '13

25 Sep '13

Do we want to move the Xen4CentOS kernel to new LTS 3.10.x from the current 3.4.x Kernel? If so, can we start testing the that kernel build? Is someone from Xen.org working on porting the xen specific patches that are required in the 3.10.x kernel from the ones we have in the 3.4.x tree in Xen4CentOS? The only one I know we need is the blktap module. I have created a new spec that builds a kernel with all the Xen configuration settings (except CONFIG_XEN_BLKDEV_TAP=m) Thanks, Johnny Hughes

Upgrade of CentOS and libvirt: need help on configuring network
by Schut, Koos J J (Koos) 24 Sep '13

24 Sep '13

I upgraded from CentOS 5.9 to CentOS 6.4. I try to reuse my virtual machines and am only partially successful: I can run them, I just cannot get the network OK and need some help with that. What I had in the past was pretty simple: both the host and the VM's used eth0 and each had an IP in the same subnet and could communicate freely. With the new install it seems somewhat more complex and I think I need to configure a bridge and use that. Unfortunately, info I find through google is overwhelming and confusing. All examples either configure something else, or the outcome is not what expected. So: how to go about setting things up to have say: My physical machine is on 192.168.0.90 My Virtual machines are on 192.168.0.100 and 101. These are to be fixed addresses. The 2 VM's have to communicate with each other and with the physical machine. The VM's do not necessarily need to communicate with the rest of the world. The physical machine needs to communicate with the rest of the world. I use: - CentOS-6.4_64 - Virtual Machine Manager 0.9.0 - xen 4.2.3 - libvirt 0.10.2.7-5 - VM's show Hypervisor = xen (fullvirt) - Emulator = qemu-dm - NIC points to Shared device name virbr0 - on the host, virbr0 has IQ 192.168.122.1 I have been fighting this for 2 weeks, now. I tried to follow several advises which resulted in either the VM's not connecting to anything, or my host losing its connection to the rest of the world, or both. So either I still do something not-right, or I follow the wrong gidelines. Can someone give me a push in the right direction, please? Koos
