I haven't followed this thread that closely, so hopefully, I'm not suggesting something that has already been discarded. Say the host is called kvmserver and your guest is called kvmguest. While on there, with ssh session virsh vncdisplay kvmguest It will tell you if its on display 0, 1, 2, or whatever. Let's say it's on 0. On your local machine ssh -L 5900:localhost:5900 kvmhost Now, if you do vncviewer localhost, it will open up a console on the remote kvm machine. If running virsh vncdisplay kvmguest shows 5901 or 5902, then change the 5900 to that number, and change vncviewer localhost to vncviewer localhost:1 localhost:2 or whatever. -- Scott Robbins PGP keyID EB3467D6 ( 1B48 077D 66F6 9DB0 FDC2 A409 FA54 EB34 67D6 ) gpg --keyserver pgp.mit.edu --recv-keys EB3467D6 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I am running putty from Windows. I do have X11 forwarding enabled. But I
still get 'could not open display' I though perhaps I needed to install
Xming, but I don't have admin rights on the Windows box, so I couldn't do
that.

[CentOS] Thinkpad T30
I have an IBM-refurbished T30, which has handled Fedora well, up through F18. But it never took to F19. I'm in process of trying to downgrade, but that seems to be a monumental job. I have other computers, including a T43 and a System76 tablet; the T30's chief virtue is that it has a serial port. My GPSs and proprietary software still use the serial port, and none of the various USB adapters I've tried have done any good. But, way back when, I mapped a lot of hunting spots and game trails. I want to keep that data. Has anyone run CentOS 6.4 on a T30? How about Wine a/o virtualization? (I'm thinking running a virtual XP, and seldom if ever going online, except occasional quick checks for linux updates.) -- Beartooth Staffwright, Neo-Redneck Not Quite Clueless Power User Remember I have precious (very precious!) little idea where up is. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

RHEV = http://www.redhat.com/products/cloud-computing/virtualization/ Then, on top of that you'd need RedHat Storage Server. It's a stabilized build of GlusterFS with Enterprise-Support - and Enterprise-price... Also, you could try OpenStack - but I'm not sure if it's worth the hassle and if four noodes is actually enough to have a usable setup. RedHat Storage Server recommends 10G ethernet, BTW. For your setup, I'd invest more in the hardware itself (redundant PSU, more redundancy in the disks, more powerful RAID-controller with battery-backed cache, the more hardware is hot-pluggable, the better etc..) Oh, and I'd love to hear success-stories of people who actually use RHEV+RHSS.

I've build DRBD-backed shared storage using 1 Gbit network for replication for years and the network has not been an issue. So long as your apps can work with ~110 MB/sec max throughput, you're fine. Latency is not effected because the average seek time of a platter, even 15krpm SAS drives, it higher than the network latency (assuming decent equipment). > most of the VM's will be running CentOS 5 and 6, some of the VM's will > be postgresql database dev/test servers, others will be running java > messaging workloads, and various test jobs. > > to date, my experience with KVM is bringing up one c6 VM on a c6 host, > manually w/ virt-install and virsh... > > stupid questions ... > > whats the best storage setup for KVM when using direct attached raid? > surely using disk image files on a parent ext4/xfs file system isn't the > best performance?Should I use host lvm logical volumes as guest > vdisks? we're going to be running various database servers in dev/test > and wanting at least one or another at a time to really be able to get > some serious iops. What makes the most difference is not the RAID configuration but having batery-backed (or flash-backed) write caching. With multiple VMs having high disk IO, it will get random in a hurry. The caching allows for keeping the systems responsive even under these highly random writes. As for the storage type; I use clustered LVM (with DRBD as the PVs) and give each VM a dedicated LV, as you mentioned above. This takes the FS overhead out of the equation. > its virt-manager worth using, or is it too simplistic/incomplete ? I use it from my laptop, via an ssh tunnel, to the hosts all the time. I treat it as a "remote KVM" switch as it gives me access to the VMs regardless of their network state. I don't use it for anything else. > will virt-manager or some other tool 'unify' management of these 4 VM > hosts, or will it be pretty much, me-the-admin keeps track of what vm is > on what host and runs the right virt-manager and manages it all fairly > manually? Depends what you mean by "manage" it. You can use 'virt-manager' on your main computer to connect to the four hosts (and even set them to auto-connect on start). From there, it's trivial to boot/connect/shut down the guests.
