The performance under NX will nearly match a local console without ever having to worry about linux video drivers, plus you can suspend your session and resume it later, even from a different host. You can access the VM console from the vmware client (using right-mouse in the navigation pane to pop a separate window is nicer than working in the tab in the main screen) but after the network is up, ssh or freenx is nicer. Also, export an NFS filesystem from a Centos box (or VM) and mount in the ESXi servers. Then you can download install isos into that area, and map then directly into the client as you create/install a new VM. If you aren't using something like puppet or chef, you can just do the initial install from the Centos 'minimal' iso, then 'yum install ' whatever other packages or groups you want. If you ever get servers that exceed the resources permitted for the free version of ESXi (or just get tired of it), you will find that Centos/KVM will host and run the same images, even in the vmdk format. But, the VMware console and the conversion tool really are pretty nice to work with - and if the company has an experienced Windows admin and uses a good anti-virus you may find you don't really hate using it to host your VMware client and NX sessions. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

If I remember correctly (but I'm no longer at that job, so don't have access to double check) around VMware 4.x or 5.x it no longer had a Linux shell.

I wouldn't expect them to change overnight, but when they eventually buy a server with more than 32G RAM, it may be valuable to know how to continue running the VMs for free... Meanwhile, if they use exchange/outlook or other windows tools internally, that's one less battle to fight if you use the same desktop as everyone else and there is very little disadvantage to doing your real work via NX/freenx. Your desktop PC most likely already has a paid windows license anyway - if it is moderately hefty you can run vmware player there for some things and spin the images back and forth to esxi with the conversion tool. > And yes, I'm well aware that ESXi is a modified version of, mmm, is it > still RHEL 3, or have they gone up yet?

So, if I am correct, then Les has > summed it up nicely. I'm not a real expert on the ESXi command line, but I'd say that the 5.x version is more complete in terms of what you can do relating to control of VMs at the local command line or over ssh (which is now an exposed option instead of hidden away) but perhaps less linux-like (notably no perl or rsync...). I usually just start long-running VMs with the GUI client or copy them around with the converter tool and haven't tried a lot of automation over ssh, though. I do use ocsinventory-ng and there is a fusioninventory program that can pull the hardware details and VM guest list remotely and push to the inventory sever (not really supported, but the version from the remi repository seems to work). Then when you view a VM server it shows its list of guests and when you view a guest it shows the host running it - which also works with KVM and perhaps some others. Without something like that it is easy to lose track. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Getting a do_IRQ: xx.xxx No irq handler for vector (irq -1), any ideas?
I setup a CentOS 6 server to use with KVM/QEMU, and I am getting the following error a good bit, granted it doesn't seem to be causing any trouble.

[CentOS] problem with WOL
Running CentOS 6.4. Hi I have a bunch of Intel systems. Ivy Bridge Q77 chipset with 82579LM nics. I can't seem to wake them up with ether-wake. The nic driver is the intel e1000e. #ether-wake -i ethX mac-addr Once up (manually) ethtool reports Supports Wake-on: pumbg Wake-on: g I'm sure I've set the bios up properly.

[CentOS] Intel 4600 Graphics (Haswell) in CentOS 6.4
Quick question that I haven't been able to find the answer to (and not for lack of trying, believe me): Is dual-monitor display for the new Intel HD Graphics 4600 (Haswell, e.g. Intel E3-1200v3 family processors) supported in CentOS 6.4? In particular, I'm looking at a SuperMicro X10SAE; SuperMicro has already replied that triple-display only works with a VGA-HDMI-DP combo (lame) and only in Windows (lame), but had no information as to dual-display (they reported to me that only tested single-head configurations [lame] before marking it as "supported" on their website). http://www.supermicro.com/support/resources/OS/C226.cfm I already found that the Intel opensource site only has releases for Fedora 19 and Ubuntu 13, and that X.org lists the latest release as 2011Q3 and the latest support as SandyBridge: http://01.org/linuxgraphics/downloads http://www.x.org/wiki/IntelGraphicsDriver/ But the latest version of xorg-x11-drv-intel in ElRepo Extras was uploaded in March of this year, and I haven't found whether the upstream vendor backported or sideported something into the latest distribution. [Yes, I'm STILL working on the workstation configuration. We're considering putting off triple-head support to cut costs, because the dreamy NVS510 cards are expensive. It's like a morass of quicksand sometimes.] Gracias y saludos, -G. -- Glenn Eychaner (geycha...@lco.cl) Telescope Systems Programmer, Las Campanas Observatory ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

In order to manage ESXi from a browser, you need a vCenter Server Appliance (SuSE or Windows), because that's what hosts the web server to provide that functionality. $$ If you want to use only the free stuff, you can, but you must manage ESXi using the Windows viclient, of if you're up to it, ssh in and use esxcli commands. You can connect to your ESXi host with a browser and download the viclient from the main page. Jack ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Thanks for the input to everyone, and I will load the plus kernel below and give it a try.

A request to update the Intel graphics packages has been filed with ELRepo: http://elrepo.org/bugs/view.php?id=405 No ETA but once released, they should be newer than what is in EL6.

It looks like Intel 7300. According to : https://access.redhat.com/site/solutions/110053 the issue is related to Intel 5500 and 5520 chipsets. That might be the reason the patch did not work. Or it is also possible that the patch itself does not work. Akemi ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I manage vSphere and a couple of ESXi (free) hosts and use the VMware CLI tools https://my.vmware.com/web/vmware/details?downloadGroup=VSP510-VCLI-510&productId=285 In addition I'm running a VirtualBox Windows VM to access the vSphere console. Getting the vSphere console working in wine has not been done, and I don't even think the Crossover guys have it working either, I looked into that a while ago. So I would also just load up a virtualbox win machine to access it. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
