Ubuntu Servers :: KVM Guests And Host Connection - Run Two Virtual Machines
Jul 23, 2010
We got a new server with 2 network interface cards with 4 MAC addresses in total. We would like to run two virtual machines (vserver1 and vserver2); one should connect via eth1, the other via eth2, and the host (mainserver) via eth0. The content of /etc/network/interfaces is as follows:
[Code]....
A connection from mainserver to vserver1 or vserver2 is not possible; a ssh connection from mainserver to vserverx ends with a login to mainserver.

I've installed VirtualBox OSE and have a couple of guest OS setup. I am running Ubuntu 11.04 and VBOSE version 4.x (the most current). Now this installs the guest OS virtual harddrives to a folder in my home directory. How do I get other users on the same host machine access to those virtual machines within VB? Currently logging in as another user and going to Applications/Accessories/VirtualBox OSE ... the list of guest machines is empty save of course on my login.

I'm looking for virtual machine software that supports dual monitors on a Linux guest with a Windows 7 host.VirtualBox supports dual monitors only for Windows guests. VMware Player was extremely slow, so I gave up. I'm not sure it supports dual monitors, anyway. Can anyone recommend a product for what I want to do?

I have a quad cpu with 8gb ram running SUSE 10 sp2 on a raid 5 XEN host server. I have created a 250 gb partition GWMAIL in the extended partition to be the disk space for the first virtual machine OES sp1 with groupwise 8.0. I have downloaded the OS .iso's to the desktop of the host server to use for installation. When I begin to install, it hangs for 5 to 10 minutes then gives me an out of space error.

I am looking for a version of vmware that manages 2 severs at the same time and that mirrors them such that if one goes down we can still work on the second and of course it also works as a backup. Also, must work on a ubuntu server I have looked but there are so many version that I don't know which one is the best.

I have currently have a PC with 16GB of RAM. I will be running multiple virtual machines using VirtualBox. Would I get the best performance from running the VMs on a Linux host, or a Windows host?

host hibernates while virtual machines are running on it.
In my case, my Ubuntu 10.04 host hibernates nicely, but when it resumes, virtual machines are reset and their state is lost.

I have a home server that I have been running for some years and am constantly tweaking / playing with it resulting in numerous reinstalls (and upsetting the wife!). It does nothing critical but I use it mainly for:
backing up my laptop files
XBMC
ZoneMinder
Due to the number of times that I manage to break it, I have now thought about setting it up as a base system but with virtual machines looking after the seperate 'components'. The machine is an AMD Athlon 64 X2 4200+ with 2Gb RAM. First of all do you think it is powerful enough to run XBMC and ZM in seperate virtual machines? - I appreciate the more RAM the better but at the moment I am sticking to 2Gb.
I was also wondering what sort of issues may arise for the audio and video areas I will be using. XBMC currently outputs through an HDMI cable to the TV and ZM recieves video signals through a seperate video card. ( I have had my concerns in the past that there have been conflicts in the way I have set things up!). I have read a number of guides about setting a system up with virtual machines but not really found any articles about the practicalities of using such a set up at home. before I commit and spend a week pulling my hair out trying to get it all to work!

Does anyone know if there is a limit to the number of virtual guests you can have in kvm. RHEL has a limit of 4. RHEL AS is unlimited. What is CentOS?

I just installed (n this 11.2 system) vmware server (v 2.02), to have access to a few small systems. One of them is a 11.1 guest which I just upgraded to 11.3, successfully (almost).
I have a problem, though: from the host I can not ping/ssh the guest.
Guest to host works fine (including names).
Code:
The firewall is down on both sides. I don't see anything with iptraf in the guest. The IP addres of the guest is correct, unless I'm too tired to see.
Why?
Code:

I currently have a virtual host setup to accept SSL connections as follows:
Code:
<VirtualHost *:443>
DocumentRoot "/var/www"
SSLEngine on
SSLCertificateFile /etc/apache2/ssl/apache.pem
[Code].....
How would I change it so that it can only be accessed via HTTPS ??

I upgraded karmic to lynx today and I'm stuck with some weird behaviour with one of my virtual hosts. The virtual hosts under /var/www/site work but my virtual host for DAVICAL which points to /usr/share/davical/htdocs/ doesn't.
Navigation to any html pages works but php files just show up blank!
Has there been a configuration change in lynx for virtual hosts outside of /var/www?

At first I thought the Delay was normal. After looking around it seems that it's not true. I made a post here. The Problem seems to be related to DNS.
The Server in Question is not Online (as in on the web), all machines are on local ethernet. From What I understand DNS is to mask the IP like a named variable for each IP. I am still figuring out the ins and outs of a linux server. DNS is something I have little or no grasp over. So I need help in setting up the DNS for this scenario case. All guides I have seen seem to be for web servers which is where I stop reading and look for other guides. I have webmin and Bind9 installed on the server.

I've just installed LAMP. http://localhost/ page works fine. I need to create some virtual hosts. Localhost page is situated in /var/www/. It's normal for me, and I wanted to created virtualhost (in /var/www/vhost1) But it doesn't open in browser. Where is my mistake?
/etc/apache2/ports.conf
Code:
NameVirtualHost *:80
Listen 80
<IfModule mod_ssl.c>
# If you add NameVirtualHost *:443 here, you will also have to change
# the VirtualHost statement in /etc/apache2/sites-available/default-ssl

I am trying to set up an Apache2 virtual host to test sites I make from my own computer.
I used this guide to set up my LAMP and vHost, The LAMP stack seems to be working great, but I run into some problems when I try to set up a vHost
As described in the guide I
1. made a new directory in my home folder /home/[myname]/www/test.dev to put my site in (it currently contains a simple index.html file as a test).
2. In /etc/apache2/sites-available I copied the file "default" and renamed it "test.dev"
3. I edited the content of "test.dev" to look like this:
Code:
4. I enabled the site using the command "sudo a2ensite test.dev". I then restarted apache "sudo /etc/init.d/apache2 reload".
5. I edited the hosts file: "sudo gedit /etc/hosts" to look like this:
Code:
6. I restarted apache "sudo /etc/init.d/apache2 reload".
Now if I enter "http://test.dev" in my firefox's adress bar I just get the apache2 "It works!" site. What is going wrong to cause firefox to show the "It works!" page rather then my own test site?

I needed to create a virtual host for a php project I'm working on. Rather than using command line and text editors, I installed webmin to accomplish this and hopefully perform other server configuration in the future. When I created the virtual host and tried applying the changes Apache wouldn't re-start, and still doesn't restart after complete re-boot. It's getting hung up at the end of apache2.conf, which is trying to include /etc/apache2/sites-enabled/000-default.
When I look at 000-default from a File Browser, it's a linked file to etc/apache2/sites-available/default I can open both the linked file and actual file in a text editor, and it looks fine. When I view the directory, /etc/apache2/sites-available from shell, the default file isn't visible. It seems this "invisibility" is probably related to the error, which is preventing start-up. Can anyone explain why the file would be visible from the Ubuntu File Browser GUI but not from the terminal, and how I can fix so apache can recognize this on start-up?

My goal is a testing server with an apache virtual host for each site that I'm working on, with fairly painless setup for each new job.For example, I want http://site-a.mydomain to server this document root /home/client-a/site-a/public_html (or something to that effect)Ideally, DNS will use a wildcard to point http://anything-i-type.mydomain to the testing server, and apache will have a dynamic virtual host definition that will do a little magic so that I won't have to mess with DNS records or add a new virtual host each time I add a new site for a client. I'll worry about that when I get there, just put that out there in case anyone has any tips! for now I just have one little problem that's hurting my mood-
It looks like I've got my DNS server working just fine, so yay there- BUT my first attempt at adding a virtual host isn't working quite how I expected- meaning that site-a.mydomain now serves up the correct document root, but when you put http://site-a.mydomain into the browser's address bar, the address bar is then updated to http://10.0.1.100/site-a/public_html - bogus!! I must be missing an option like "FunnyBusiness Off" -
root@ubuntuvm:/etc/apache2/sites-available# vim client-a.mydomain
<VirtualHost *:80>
UseCanonicalName Off
ServerName site-a.mydomain
DocumentRoot /home/client-a/site-a/public_html
</VirtualHost>2

I couldn't find a clear answer to this, but is the linux-image-virtual package for host machines that will contain VMs, or a VM-oriented kernel for guest OS (ubuntu)? I have some guest VMs running on Microsoft's Hyper-V, and was looking for some further optimizations.

I've set up a server running Ubuntu 10.10 (desktop) with apache. Problem is: When I try to configure multiple virtual hosts I can only access the first one. I'm sure that I'm missing something basic in my setup, but I cannot seem to figure out what.
What I want is simply two virtual hosts, one only available on the LAN where I can test my php files and one "live" available from the outside.
Heres what I've done:
Installed Apache2.2
Copy /etc/apache2/sites-available/default -> /etc/apache2/sites-available/dev
Modified "dev" config DocumentRoot and Document to point to /var/www/dev
Modified "dev" config VirtualHost to <VirtualHost *:1337> (port change right?)
Modified "default" config DocumentRoot and Document to point to /var/www/live
[Code].....
Live works fine, but dev cannot connect (as if there is no server there).

I installed apache server on my Fedora 12. Its showing the test page 127.0.0.1, but when I give the address 97.168.234.76 (0r www.chaalu-kam.com), it tells that the requested url could not be retrieved.
I have made the following additions to the /etc/httpd/conf/httpd.conf file
Code:
NameVirtualHost 97.158.234.76
<VirtualHost 97.158.234.76>
ServerName www.chaalu-kam.com

I'm not sure is this is possible or not, but what I would like to do is take my public address mydomain.com and configure a virtual host something.mydomain.com only instead of having the content on the same server I would like it to point to the IP of my virtual machine that is in my private network and display that page publicly. Does anyone know if this is possible, or how to do it? I have done this with port forwards, but would like them both to be on the same port.

If I go to a virtual host it asks me if I want to save "index.php" (Typing in the host name followed by index.php also works). But if I go the main site it does not. This happened after an upgrade to Ubuntu 10.04
Here are some additional details - apachectl -M shows rewrite_module (shared) the host config file has AllowOverride All the dir and php5 modules are loading fine.
