Software :: Put Some Virtual Machines On My Fedora13 Box

Nov 18, 2010

I am attempting to put some Virtual Machines on my Fedora13 box. Using KVM it just doesn't want to work quickly.... Using the v.14 LiveCD to try and install an image onto the virtual machine... took over 15 mins to get to a login screen, then I gave up attempting to log in after 5 mins from clicking the login button. I assigned the virtual box to have 1024Mb RAM and access to both CPU.

I then decided to sack it off and try and install VirtualBox... this has been a disaster. I know it's due to the fact that it wont run alongside KVM, and I've disabled KVM (as far as I am aware) - but it's still FAILING on using DKMS (Or whatever it's called - not got the error open at the mo). basically.. am I doing something wrong causing the system to run so ridiculously slowly, and how am I being thick for VirtualBox to fail to install?

OpenSUSE :: XEN Virtual Machines Only Available For Root?

Jun 26, 2010

I installed openSUSE 11.2 and works great. The only problem I have is that I can use the XEN virtual machines only as a root. If I login as a normal user and open the Virtial Machine Manager I receive the following message:Virtial Machince Manager Connection Failure:Unable to open a connection to the Xen hypervisor/daemon.

Verify that:
- A Xen host kernel was booted
- The Xen service has been started

General :: What Are The Limitations Of Virtual Machines

Jan 4, 2011

I'm considering setting up a virtual machine running Windows, with Ubuntu 10.10 as the host OS, for those cases where I have a Windows-only program.I understand that using a VM will lose some performance, but are there other limitations to what the OS in a virtual machine can do compared to "running on bare metal"?

For example:

Can a VM play games, like Dragon Age Origins or Civilization V? (Possibly with poorer framerates and/or lower resolution, but does it play at all?) Can a VM rip DVD/Blue-ray using AnyDVD or similar Windows program? Can a VM handle new hardware that requires dedicated drivers, but the drivers are only available for the OS running inside the VM? (Ex. graphics card, digital camera, card reader for smart card authentication.) Is it possible to say anything about "general limitations" of VMs, or is this wholly dependent on the specific VM?

Fedora X86/64bit :: 64-bit Vs 32-bit Virtual Machines Trying To Run 11 On VMware WS 6.5.2

Aug 14, 2009

I have an HP Compaq nx6125 laptop, which has an AMD Turion 64 2200MHz processor, running Windows 7 Ultimate. I have installed the VMware Workstation 6.5.2 [full] trial and am attempting to install Fedora 11 on a virtual machine.

I understand that the Turion processor is a 64 bit processor, so I downloaded the Fedora 11 x86_64 DVD iso image.

First I have to create a VMware virtual machine (VM) and choose a version for it. If I choose a version that is any of the 64 bit options (for example, "Other Linux 2.6.x kernel 64-bit", since there are specific options for RHEL but not for Fedora), I get an error message the moment I try to power on the VM and start the install, saying "The buslogic SCSI adapter is not supported for 64-bit guests in this release [...]". Then the VM just shuts down.

I guess this laptop does have a SCSI bus, but my disks are IDE and as far as I can see (System Information) the SCSI bus is not used (?).

On the other hand, if the VM I create is any of the 32-bit option versions, I get what seems to be just a warning, saying that I'm running a 64-bit guest OS (Fedora 11) on a virtual machine configured to run a 32-bit OS, and suggesting I change this to ensure the 64-bit guest OS will function correctly. What would be the risks / downsides of forcing the install anyways?

I will also ask for help on the VMware side, too, and it's not my intention to turn this into a VMware discussion, but I'm just wondering if anybody on the forum has worked with this combination (VMware 6.5.2 and Fedora 11 running within it, preferrable on an HP Compaq 6125 running Windows 7 Ultimate) ? If so, I'd really appreciate some feedback / pointers.

I used to work a lot with Linux back in the days of RH5.2, and it's been a while, plus I'm new to the virtual machine world, so bear with me here.

OpenSUSE Network :: Set Up 3 Virtual Machines On A Server

Dec 10, 2010

I only have one IP adress to access the server. But the server will host 3 web sites and I want them to be hosted in a vm. So, I want to setup 3 virtual machines to do it and use apache reverse proxy and vhosts to redirect the domain requested to the right vm. Now. I understand the concept, but I am not an expert to set that up....

I have an openSUSE 11.3 server. So, I have to set a virtual machine server, is that right? I have been told that I cannot do it with VMware server in oS 11.3. Can I use virtualbox for this? I only have to install virtual box? Is there a special version to install? Once the virtual machine server is install, is it trivial to create 3 vm? So, I want to know wich are the steps I have to take to set that up.

Debian Configuration :: Setup Some Virtual Machines That Will Use The Same Architecture?

May 31, 2011

I want to setup some virtual machines that will use the same architecture and debian-version as my host-machine. I have started to setup VMs with a netinstall-image and now want to add more software using apt-get. As most of the software I will use is already installed on my host-machine I wonder if there is any way to configure apt in such a way that it will not download packages from the internet, but will use the packages from my host-machine to save network-traffic. Is there a good may to populate VMs using the debs from the host-machine.

Fedora Networking :: Isolated Network For Virtual Machines?

Oct 10, 2010

give a reference to the definition of 'isolated network' as used in the Virtual Machine Manager? I have virtual machines that I do not want to have access to the host, I thought 'isolated network' did this but the VM's can ping the host. If (probably) I am wrong, how can I create an network that can not see anything else but what is also on the same network? The host and the isolated network are 192. and 172. The virtual bridge is not connected (or so it says) to any physical device.

OpenSUSE Network :: Disconnected Machine With Virtual Machines?

Aug 29, 2011

I have OpenSuse 11.3 with VirtualBox on it, and with installed Oracle DB (on host OS).. but, sometimes this computer is disconnected, without it's gateway (adsl router)... and in that case, I cannot ping from virtual OS to host OS, or another virtual OS. I tried to use 'Host only' option within VirtualBox, but it doesn't work. What should I do? It seems that virtual machines requires some kind of gateway/router, but since machine is disconnected, it's not working.. how could I fix it?

Server :: Installing Distro And Running Virtual Machines

Jun 27, 2009

First off I am new to Linux and fairly new to working in Networking and Server config's. I have been using Windows for years and have been learning Windows Server 2003 as I have a Technet account, I can get any MS software. I would like to learn Linux and use this as my Server environment. My project looks like this: I have a Quad core, 8gb machine. I want to install a distro of Linux (server or desktop) and run Virtual Machines on it.

My perferred way would be to use Virtual Box but I could use VMware products if that was better. I would like to run WS2003, WS2008, Linux Distro and anything else that will run in a VM. I can figure out that part pretty easily. I want the Linux host machine to run all these VM's and access and use them on my MAC remotely. I have done some research on ESXi as well, but I don't think my Hardware is going to support that. My exact PC spec's are:

AMD x4 940
8gb DDR2
Gigabyte MA770-UD3
2 Velicoraptor Drives
GTX 260
I will be dual booting this machine on one of the Raptors for gaming as well.

Fedora Networking :: Block Virtual Machines Access To Server

Nov 10, 2009

in my network, users has total access to their PCs, so theres a problem to filter (URL, ports,etc.) their virtual machines installed (they can assign self any IP, e.g.)

Id thought about use the MAC prefix in VMware VMs (00:0c:29:*), but i can only found a way through DHCP, and this isn't a good solution (they can assign a static IP to workaround...)

It will be better using firewall (iptables), but I don't found the way to add rules based in MACs with wildcards.

General :: DHCP Server Inside A Virtual Machine Can't See Other Machines

Jun 2, 2010

I setup a private network from virtual machines and one of the machines is the DHCP server for the group. I want to specify a next-server for the DHCP server but I'm having trouble connecting to any of the machines that I lease IPs to. I'm just trying to do a simple ping/ssh to 10.0.0.252 (a machine with a lease) but it doesn't seem to respond. I'm assuming I need to be able to connect to my next-server but maybe I'm wrong.

CentOS 5 Networking :: Gathering Network Usage Of Xen / Virtual Machines?

Jun 23, 2009

I've run into a problem gathering usage for my xen virtual systems. With my old model I used to gather all network usage via my cisco devices using the the counters for each port. Each system had it's own port on the switch, and I tracked network usage accordingly. Now that I'm using xen for virtual systems, and multiple vm's share the same switch port, i'm not exactly sure what my best option is for tracking usage.

I thought I may be able to setup vlans on the switch, and bind each vm to a different vlan using vconfig... but it seems like there has to be a better solution than that.
