KVM or Xen for GPU passthrough?
location: ubuntuforums.com - date: November 26, 2012
For years I've used VirtualBox to successfully run XP and Vista clients on my Ubuntu box, and am considering taking the next step to either Qemu/KVM or Xen. Have always toyed with the idea, but never made the switch because VirtualBox is so easy to use whereas KVM has always suffered from the typical Linux obscurity/learning curve. Reason: AFAIK VirtualBox is a type 2 virtualizer which runs on ring 1 whereas KVM and Xen are type 1 virtualizers running on ring 0. This allows KVM and Xen to at least theoretically pass through PCI devices to the virtualized client, thus bypassing the translation layer that type 2 virtualizers like VirtualBox must use. At least, this is what I've been able to gather from Wikipedia and some research on the net. I may be totally off base here and spouting meaningless nonsense.
My goal is to pass through client video demands to physical hardware rather than the emulated virtual graphics adapter. I understand that Xen now does this (with a lot of blood, swe
kvm or xen ? suse or rhel ?
location: linuxquestions.com - date: August 18, 2010
I have tried kvm/xen on RHEL5 so far.
Kvm works quite fine altought its quite poor (compared to citrix or vmware). xen on RHEL5 did'nt seem to be very reliable..
Wanted to ask , is it same with SUSE, or are SUSE's kvm/xen maybe somehow "better" ?
Also, is there good administration utility for kvm/xen? So far I have only used virt-manager in RHEL5.
Thanks in adv.
[SOLVED] KVM or Xen?
location: linuxquestions.com - date: July 8, 2015
Currently my server is doubling as an HTPC with Kodi. It is running Ubuntu 14.04 Server with KVM.
I have been trying to work out a web based kvm management for a year now with zero luck. WebVirtMgr guide doesn't work at all, Kimchi can't autostart the vms, and anything else is so complicated to install that I haven't gotten anywhere all this time. The reason I want web based management is I am back to Windows on my laptop and have no desire to go back to Linux as a daily driver, so of course I no longer have virt-manager. Wouldn't mind being able to manage from my tablet or phone as well.
Doing some reading I found that with Xen and the XAPI the XenCenter app for windows will manage the virtual machines just fine. However I also need the host to direct boot to Kodi for htpc purposes.
What kind of options do I have to be able to keep vms on my server, managing them from Windows? Currently I'm doing it with Kubuntu in VirtualBox and virt-manager. However 120gb ssd, don't like having 1
Citrix XenServer or Xen on CentOS
location: linuxquestions.com - date: June 9, 2010
Was thinking about using Citrix XenServer but turns out that after installing the XenServer we still need to install a Linux Supplemental Pack in order to create a VM. After looking at CentOS's Wiki, appears that creating a VM using CentOS's built in Xen server isn't too difficult and allows me to use one vendor product. Any pros and cons against either Citrix XenServer or CentOS's built in Xen server?
Seeking thoughts RE: moving from CentOS+VMware to.... Xen? KVM?
location: linuxquestions.com - date: July 21, 2010
I've a machine that has a AMD Phenom quad-core, 8 GB RAM, 2 - 1TB drives using Raid-1. And on this I'm currently running CentOS 5.3 64-bit and under it I'm running VMware Server 2.0.2; Oracle 11g R2, Apache 2.2, JBoss 5.0, and some other things I like.
I'm stuck on this CentOS because of the issues using VMware Serve on Fedora, etc. What I do like about VMware is that it's utility package is mature and as long as you stay on a kernel it knows, it just works.
However, that is boring and I haven't had to rebuild my machine in at least 6-months.
One of the things that scares me about moving to Xen or KVM is the networking part. What I see in the documentation is a flow that doesn't look correct to me (overview; install xen, virt packages; install virtual clients; configure network). Why wouldn't you configure the network before the client installation? Why does the Bridge networking eliminate the use of the original IP address associated with the NIC? Should I use a alias (et
CentOS, Fedora, or Ubuntu for server. Which is best?
location: ubuntuforums.com - date: May 20, 2008
The title sums it up. And, posting this on an Ubuntu forum, I know beforehand that the answers might be a little biased.
But the gist of it is that I may soon need to set up and periodically administer a box that will be used for subversion, among other things. I've been using Ubuntu since Feisty on might desktop and have loved it overall. My first instinct is to go ahead and load Hardy LTS on the new server, but then again Fedora seems to be the go-to distro for servers.
I realize that Canonical is working hard to make Ubuntu a server household name in its own right with some already evident success, but I know Fedora supposedly has a history of being a strong server platform, and nearly every server I've seen in the past is usually running some form of Red Hat-inspired software.
Come to think of it, I had forgotten about CentOS. How does that stack up?
I haven't really administered a server of any kind before, so I'd appreciate honest assessments of each distr
enterprise mail server in centos 6 or ubuntu 10.04
location: linuxquestions.com - date: October 25, 2011
I need to configure an enterprise class secured e-mail server by using postfix (I don't want to use zimbra, I just want to get out of zimbra) in Centos 6 or Ubuntu 10.04 server. I need the following features in my mail server.
POP3 and IMAP access for users, mail forwarding, SMTP authentication for all out going mails, able to set quota for individual user mailbox, able to define e-mail attachment size for individual user, user themselves can be able to set automatic vacation response, Group e-mail, able to block certain kind of attachments in the e-mails, Squirrel Mail or roundcube as the web client. I have planned to configure licensed version of kaspersky antispam and antivirus for security.
Also I need to configure jabber chat server in the same machine and all the user has to login to their chat client using their e-mail ID and their password which i was created in the mail server, in simple words common authentication for both e-mail and ch
KVM or Virtualbox for Windows 7 guest??
location: ubuntuforums.com - date: January 21, 2013
I want full internet access and preferably USB printing too so I know I need to use the Vbox from Oracle directly and not the Ubuntu repos.
But what difference in performance would I see between the two? I've used Virtualbox a lot so I know how to set it up well, but KVM I've only tried a few times. Can the screen resolution go beyond 1024x768 or whatever it is?
What benefit is there to having KVM be part of the kernel? KVM seems like it's a lot more difficult to set up. The host will be 12.04.
help me choose. vmware esxi or xen server or hyperv
location: linuxquestions.com - date: August 18, 2011
I wanted to setup a new virtual environment at work on a server and an older san. This would not be a production setup.
We currently have esx 4.1 in our production. And we also have hyper-v in another test enviroment. However, I was thinking of getting rid of the hyper-v and setting up xenserver.
Does anyone have any thoughts on this? Should I stick with hyper-v or go with xen server. Or should I just make our whole virtual network run on vmware, even though the free esxi cannot be managed via v-sphere?
Is CentOS RHEL or RHEL Server?
location: linuxquestions.com - date: February 28, 2006
As the title says... is CentOS based off of plain RHEL or is it based off of RHEL AS or RHEL ES?
