similar to: bridging to a bond in KVM

Hi all, Don't mean to double post as I sent this to the general Centos list. But, does any one have 802.3ad (mode 4) working on there Centos6 KVM setup? This would be a bridge+bond setup of course. If not possible, would I still bond the interfaces on the switch and then bond them in the guest rather then from within the hypervisor? - aurf

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

With the current talk on bonding, I have a few questions of my own. I'm setting up a KVM host with CentOS 6.3 x86_64 on which I'd like to attach the VMs to a bonded interface. My target setup is one where two GigE NICs are bonded and then the KVM bridge interface is attached to the bonded interface. Initially I tried to use the balance-alb mode (mode6), but had little luck (receiving

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

Hi, This may sound crazy but I will go ahead anyway. Here's my scenario: ifconfig bond0 10.10.10.1 netmask 255.0.0.0 ifenslave bond0 eth0 ifenslave bond0 eth1 brctl addbr stp0 brctl addif stp0 bond0 brctl stp stp0 on Is this a valid scenario? I am trying to bond two interfaces and run STP over the bonded interface..The problem I am trying to solve is to run STP over aggregated links

Hi all, Does any one have 802.3ad (mode 4) working on there Centos6 KVM setup? Of course we are also bridging here. - aurf

Hi, I've been using qemu-img resize for a few days now, seems fine. But if I du the VMs image file, it still shows the size before resizing. Inside that VM, the new size shows correctly. Is qemu-img resize the right tool for this? Once I qemu-img resize, I then use various fdisk/ LVM tools, etc... to resize within the VM just incase you all were wondering. - aurf

Hi, I'm VNCing into my KVM server and opening virt-manager. When trying to manage a newly created guest, I'm finding the mouse pointer stays on the outside of its virtual machine window. Any insight as to why its tracking so oddly? Thanks in advance, - aurf

Hi, Has any one had problems with mail clients were your DNS is like this; doman.com MX 50 mail.domain.com domain.com MX 100 mail2.domain.com domain.com CNAME www.domain.com -aurf

Hi all, I've a particular host on my network that when I run; rexec -l username -p password remotehost command it just hangs. When I do; rexec -a -l username -p password remotehost command i get; Where are you? If I do; rexec -l username -p password localhostname (not just localhost but its actual name) command it works. Any ideas would be very appreciated. - aurf

Hi all, I've a 30TB hardware based RAID array. Wondering what you all thought of using ext4 over XFS. I've been a big XFS fan for years as I'm an Irix transplant but would like your opinions. This 30TB drive will be an NFS exported asset for my users housing home dirs and other frequently accessed files. - aurf

Hi, I ran gemu-img on a VM thinking it was down but in fact it was live. I rebooted the VM and it does show the added space after running pv/lv etc to resize the disk, also the KVM server if you will, also shows the correct new size of that particular VMs raw file via du. However the virtual machine manager still shows the disk size of that VM as being before the resize. Is there a way that I

Hi all, I am migrating my Xen guests over to KVM. Does any one know were I can find said 5.1 kernel for download? - aurf

Hi, I'm new to the list and new to Xen, so please be gentle with me! ;-) I've got a CentOS 5.2 x86_64 machine with two interfaces (eth0 and eth1 unsurprisingly) bonded into bond0 in mode 4, and a Cisco switch set up with LACP to suit. I didn't select Xen at install time as I wanted to install Xen 3.3.1 from the gitco repo. After installing and yum updating, I added the gitco repo

Hi all, Taken from this link; https://www.centos.org/modules/newbb/print.php?form=1&topic_id=34988&forum=55&order=ASC&start=0 Seems like I am having the same issue. I assigned my boot loader to be on /dev/md0 rather then the default of /dev/sda1 Does any one have insight to this? Thanks in advance. BTW, I have no swap partition and will do a swap file instead, easier to

Hi all, I never really paid attention to this but a file on an NFS mount is showing 64M in size, but when copying the file to a local drive, it shows 2.5MB in size. My NFS server is hardware Raided with a volume stripe size of 128K were the volume size is 20TB. My NFS clients are the same distro as the server being Centos. Is this due to my stripe size? Nuggets are appreciated. - aurf

Hi all, I noticed that my ssh logins to a particular server were taking up to 5 seconds to finally login. My tcpdump -vv weren't producing much output (not good) and my pings to and from that host were normal and almost identical to other hosts on my subnet that had no ssh login delay issues. Log files also showed nothing alarming. My hosts file was missing this at the very end of

Hi all, I'm migrating from my Cent 5.x LDAP server to Cent 6.x. But wondering if there are any advantages to the Directory Server package itself? Been using regular old LDAP server for years now. I manage it both via Webmin and command line as well as some tweaks to a Drupal module. The fail over has always sort of bothered me as the secondary LDAP servers pull vs being pushed to, at

Trying to think this through, hope someone can lend a hand. I have 3 eths I want to bond together and that seems simple enough. eth0,1,2 <-> bond0 , though not sure how this would be for multiple ip addresses needed for the virtual machines... perhaps eth:0, eth:1 etc....to bond0:1, bond0:2 ? then I want to bridge to my virtual machines.... I am going to be using virtual machines, each

Hi, Firstly I apologise for the cross-post, however I don't expect to get as quick a response from the package maintainers as I do from the Debian community, and this issue affects a service that I've got scheduled to go live at midnight this evening. :( A recent update from xen-hypervisor-4.1-amd64 version 4.1.3-7, to version 4.1.3-8 on Debian Wheezy has caused all vm's on this host
