Hi all. I've been playing around with KVM for a bit now and have several virtual machines up and running. Having passed what I considered "first look" stage, I'm ready to start using libvirt as a manager. For reference, pre-libvirt, I have started this VM with: /kvm -net nic,model=virtio -net tap,ifname=tap5,script=no -drive file=test1.img,if=virtio,boot=on -curses

Numerous how-tos all over the Internet show how one would set up a tunnel using ssh, e.g.: ssh -f -o Tunnel=ethernet <server_ip> true I was wondering if there's a way to subsequently acquire the names of the local and remote tun/tap interfaces (e.g., using the default "-w any:any") for subsequent automatic tunnel configuration, e.g.: ip link set $TapDev up ip link set

Alas, Virtmanager doesn't seem to be a supported program under Gentoo - the distribution I use. If its X-based, it wouldn't work anyhow - I'm strictly a command line shop. > > Once

Hi All, I am facing an issue regarding communicating a value from outside to a Guest OS (linux, solaris and windows) launched on Xen Server. I did went through this thread, but It was not completely clear. http://lists.xensource.com/archives/html/xen-users/2006-07/msg00473.html My question is - Is there a way in Xen, through which I can communicate a value from outside to a Guest OS (linux,

I inherited a xen server that is setup to have all the VM images hosted on an iSCSI mounted NAS array. We been experiencing a random (about every 2-3 days) issue where xen would crash all the VMs, leaving nothing but the Domain0 running. What appears to be happening is something causes the iSCI mount to hiccup. Running "vgchange -a y" and restarting all the VMs brings everything up.

I have two problems where I've come up with some code that will do the analysis that I want, but it looks pretty clumsy. In the first case, I calculate the variance on five different columns for each of 14 clusters and get them into one matrix. I get the job done, but I would have thought that it could be done in one or two lines, not six, and be generalized so that it didn't matter how

I've been playing around with qemu and wanted to make the guest OS instance visible on my network. This meant getting bridging and tun/tap working. After getting things working by pasting command from the CentOS wiki article plus adding a few enhancements, I decided to capture the process in a shell script that would be suitable for a user in the sudoers file to fire off. Not sure why

I am following directions in http://wiki.centos.org/HowTos/KVM#head-c02a0b33e7949b0bc3b151ac6e0bdfb91b6bbd1c it says do yum install bridge-utils - works fine, they yum install tunctl does not find anything. yum provides "*/tunctl" does not find anything I am using 5.4 x86_64. Is this howto out of date? How do I get tunctl? Thanks, Jerry

OK, this should be an easy fix but I can't find it, and it's strictly a cosmetic's issue. on our older Gentoo systems if you do an ls -a it orders the results with all the . files ordered alphabetically then all the non-hidden files alphabetically. it also sorts with capitals first. on the new Centos 5.3 systems ls -a returns all the files sorted alphabetically with

EPEL doesn't have uml_utilities and NUX doesn't have tunctl.

Which repo has tunctl for CentOS 7 ?

Hi! I have many problems getting this thing to work. There''s a host with two network interfaces, where there are two routers to Internet in two separated networks. The host uses multihop routing for deciding to which router send the packets... but the routing decision is wrong made. Some packets with source address of one NIC, go to other network. I have a host with three NICs in it:

It looks like uml_utilities, which is where it is in CentOS6 EPEL and Fedora, isn?t built on CentOS7?s EPEL. It looks like the Nux repo has a ?tunctl? package though. -- Jonathan Billings <billings at negate.org>

Hello, I am creating a configuration where a Redhat server running bridge-tools 0.9.5 will be bridging between different VLANs on the same physical interface (for example: a bridge consisting of eth1.100 and eth1.110). This physical interface is being connected to modern Cisco switches running PVST+. The Cisco switch does not like this configuration as the tags on its BPDUs are being changed

Is anyone using sk98lin Gigabit Ethernet adapters under CentOS 4.x? The version of the driver that ships with CentOS 4.x kernels was too old to support the onboard NICs on some Intel server boards that we recently got, so we installed a newer driver using DKMS. However, we're having problems finding a stable driver to use: the first version that we tried (7.09) gave a kernel panic when I ran

I sent it first from an non-subscribed address, don't know if that'll get to the list or not --JJ> Hi folks, I have an implementation question regarding bridging on a linux box between a catalyst trunk port and a cisco 26something w/802.1q subinterfaces. So right now, there's no vlan trunking going on on the link my bridging firewall sits

Dear, I''ve attempted to upgrade a Xen box from 3.1.2 to 3.2.1. Unfortunately it has been a partial success only. At this point I''m really stuck with a network problem that affects my HVM machines (Linux PV run fine). The really odd thing is that everything seems to work properly, except that the "vif" network interfaces in dom0 seem to have only dropped TX packets for

Sorry if this off-topic but I have a qemu related question I was going to send to the qemu users mailing list but that list appears to have vanished. I thought this community might have some insight. I am interested in controlling VM access to different tap devices so I want to have different qemu processes bound to different tun devices. I've created new tun devices (eg. /dev/net/tun_low)

We should prefer `const struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch. A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // <smpl> @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const
