Hello, If you''re interested in running Xen 4.0 hypervisor/dom0 on RHEL6, take a look at here: http://wiki.xen.org/xenwiki/RHEL6Xen4Tutorial It explains steps needed to rebuild Xen 4.0.1 src.rpm from Fedora on RHEL6, and how to fetch dom0 capable 2.6.32.x kernel from upstream git repository. It also shows how to get libvirt/virt-manager working with Xen on RHEL6. Hopefully it helps :)

HI Michal Thank you for explaining. I have this situation in a number of production servers where we would always use static IPs for the host and VMs. In such case we have no requirement for NATed network in the future. And we we ever do, we can rely on a DHCP server within the LAN to provide IPs to the VMs. I'll look to remove both libivirt-daemon-driver-network,

Hi. I have a machine with a local DHCP server and a couple of virtual networks and I've configured the server for each virtual interface, so that I would be able to install VMs on the corresponding subnets using PXE. The problem is that the two DHCP servers (my local server and dnsmasq) are conflicting with each other causing the boot process to either fails or takes ages untill a VM can

hi users I have my dhcpd to serve nothing but virbr0 (libvirt), OS is Centos 7.2 Dhcpd would not start, complaining like this: No subnet declaration for virbr0 (no IPv4 addresses). ** Ignoring requests on virbr0.  If this is not what    you want, please write a subnet declaration    in your dhcpd.conf file for the network segment    to which interface virbr0 is attached. ** ##SELECTION_END## and

Hi, Does anyone know what version of XEN works fine with CentOS 6? I installed XEN on a CentOS 6 server, as per these instructions: http://www.crc.id.au/xen-on-rhel6-scientific-linux-6-centos-6-howto/ And the server now gives this error on reboot: PANIC: early exception 0e rip 10:0 error 10 cr2 0 These are the packages that was installed: Installed: kernel-xen.x86_64 0:2.6.32.45-1

Hi all, I have 3 guests (2-RHEL4 and 1 RHEL6) and have some issues regarding networking between them. The 2 RHEL4 system's use default bridge virbr0 and get ip's of range 192.168.122.0/24 (192.168.122.207, 192.168.122.167) I created another bridge (virbr1) with NAT forwarding (no dhcp). The network i choose was 192.168.100.0/24. And the third system (RHEL6) was assigned static ip-addres

I am running Fedora 16 64bit and installed libvirt. I have the VM running with arm emulation with this one issue I can't figure out. I used Virtual Machine Manager to manage the VM and can access its console there. The Ethernet appears to be eth1 and the guest can set an IP on it etc. However, I cannot see any traffic from the Host when dumping any of the interfaces. I've tried

Hey, I''m more a reader than a poster on this list but Recently I installed CentOS 6.2 with myoung XEN Dom0 kernel and 4.1.2 hypervisor, at first everything went smooth, DomUs run like a charm and so on, but my serial console is gone for good tried dmesg | grep tty which spits out: uname -r 2.6.32-131.21.1.el6.xendom0.x86_64 dmesg | grep tty console [tty0] enabled Weirdest thing when

Hi all, I want to set the advertised value of MTU for virbr0 interface on a Fedora 21 host to 1454 to accommodate the installation of new VMs for testing purposes. The aforementioned host is an OpenStack VM actually, which explains the need for a lower than 1500 MTU. I noticed Pieter Hollants' patch to set dhcp-option=<number>,"<value>" for an interface, but

Hi Everyone, I am trying to setup xen3.4.1 FC12(xendom0) on top of FC12 freshly installed. I am using DQ965GF intel mother board having intel VT-x enabled.

I did few googlings

At work I have a script that provisions a vm for use by employees. One step in this process is to fetch hadoop, which we happen to get from cloudera. I noticed the script always failed when I used libvirt's default networking (nat) but worked fine when I used user mode networking. My instinct is that this is related to (potentially uncommon) network traffic from the server in question, and

Hi, we would like to establish a small Lustre instance and for the OST planning to use standard Dell PE1950 servers (2x QuadCore + 16 GB Ram) and for the disk a JBOD (MD1000) steered by the PE1950 internal Raid controller (Raid-6). Any experience (good or bad) with such a config ? thanxs, Martin
