CentOS-6.5 We have a KVM guest running MS-WinV7pro. This guest is joined to an Active Directory Domain. That domain provides DHCP to the members. The KVM guest does not obtain its IP from the domain but from the local host's qemu hypervisor instead. Is there anyway to get around this and have the guest MS-Win OS get its DHCP from the same place as the rest of the domain members? -- ***

Hi, Wondering if this is the proper bridging technique to use for Centos6+KVM; http://wiki.centos.org/HowTos/KVM Before I embark on this again, I would like to do it by the book. Thanks in advance, - aurf

Almost exactly two years ago, I released the first tutorial for building an HA platform for KVM VMs. In that time, I have learned a lot, created some tools to simplify management and refined the design to handle corner-cases seen in the field. Today, the culmination of that learning is summed up in the "2nd Edition" of that tutorial, now called "AN!Cluster Tutorial 2".

Hi, I have two KVM hosts (CentOS 7) and would like them to operate as High Availability servers, automatically migrating guests when one of the hosts goes down. My question is: Is this even possible? All the documentation for HA that I've found appears to not do this. Am I missing something? My configuration so fare includes: * SAN Storage Volumes for raw device mappings for guest vms

I'm creating a firewall HA cluster. The proof of concept for the basic firewall cluster is OK. I can bring up the cluster, start the iptables firewall, and move all of this with no problem. I'm using Conga to do all of this configuration on Centos 6.3 servers. To extend the "HA" part of this, I'd like to use bonded channels instead of plain old NICs. The firewall uses

Hi, I am doing xen in box gsoc project. The aim of the project is to have custom installer ISO which delivers xen stack running on c7 along with necessary bridge networking configuration. But I am getting confused over how to package bridge networking settings, so that I can deliver that during installation itself. I can use bridge-utils and package ifcfg-* files as differnet package. But for

I've got a situation here where my LVM is showing the following problem: Found duplicate PV xxxxxxxxxxxxxxxxxxxxxx: using /dev/sdb2 not /dev/sda2 Not sure what causes this and I really don't have a clue as to what the consequences are when seeing this or how to fix it. Google just confuses me with any suggestions. Can anyone offer any help, please? Steve Campbell

Hello, i'm trying to create some best practices on my centos 6.3 / libvirt /kvm hypervisors. Actually, i use NFS as shared storage backend for every VM and make reasonable use of the KSM (enabling it into qemu.conf). Every VM is configured with VirtIO drivers (when possible) and the disks use none as cacheing method to allow me live migration. I'll be happy to know if there are some

took a couple months off due to road blocks, hoping a fresh look would allow me to use my server as desired. I have three ports, eth0-2 over two nics. I want to bond them, and then use a bridge to connect to virtual machines on the virtual host computer. Never having done this, I am confused on some parts. Here is where I am at now and any pointers helpful. Single server, centos 6.x My issue

I have a computer I am using to host a virtual machine. Centos 6, for both, 64 bit. The host machine's network connection seems fine. No problems. Trying to access the virtual machine is usually fine. but then, poof, ssh, http, ftp, all lose connection for about a minute. Then they come back up. I looked in all the logs on both machines, could find nothing, but not sure where to look. My

so I have a bunch of servers at work that are on DUAL UPS's (1 per each of 2 power supplies). Its mostly HP gear, but also some Sun and IBM. Ideally I'd like the system to not go into shutdown unless BOTH UPS's that a particular box is plugged into (there's actually 4 UPS, 2 per each of 2 racks). Has anyone ever configured anything like that with NUT or whatever? Right

I have seen those documents, I did not see anything that indicates how _automatic_ bridge configuration could be enabled with xl. For my specific set up I have two bridges (xenbr0 -> peth0 & xenbr1 -> peth1). If I have to configure this manually with ifcfg scripts I will, but if an automatic method is provided or is possible with xl I'd prefer to use that. -Gene On Thu, Jan 29,

Hi all, I use CentOS5.x + Xen in production for virtualization. I use it with bridged vlan networks and bonding (active-backup) like that: eth0 eth1 | | ------- | bond0-------bond0.10---------bond0.12 ... | | | | vlanbr10 vlanbr12 dom0 | | ------------- -------------- | |

Hi all, With help from others, I''ve been able to get Olaf''s patch for enabling MTUs >1500 for vifX.y and tapZ devices working. I''ve been able to boot dom0, launch domU and live-migrate without having the bridge''s MTU degrade at any time. Would the Xen RPM maintainers (and others) mind taking a look at the following patches? Kernel part:

I've got a Centos 5.8 box that I use for testing Xen VMs. I'm trying to setup some Centos 6.2 hosts in a high availability situation. I've tried the pacemaker route and couldn't get the connection established, so thought I'd try the RH-preferred methods. Mind you, all of these VMs are on the same host. Using Conga, it seems that I need some sort of fencing device, which

Hi all, Read many posts on the subject. Using 802.3ad. Few problems; Cannot ping some hosts on the network, they are all up. Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts. Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway. When cold booting it somewhat works, some hosts are pingable while
