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.

I now have 2 desktops running debian. I have virtual servers running in desktop 1, and I am hosting my photos using Gallery2. I have copied Gallery2 and the mysql over to desktop 2. I have entered port forward to desktop 1 using port 80 (using my router), and desktop 2 using port 1000. I can only access Gallery2 in desktop1. If I tried to access Gallery2 in desktop 2, I got re-directed to desktop1.
Questions:
1. Are home routers capable of port forward to more than one computers in a home network behind the firewall of the router? It is Belkin N+ router.
2. Can multiple virtual servers be setup in 2 desktops?

I am new to networking and trying to setup my own local area network using virtual box machines. I have installed BIND 9.7.3 using yum in Fedora (dns server) and created all necessary .conf and zone fil es. I am successfully able to resolve domain names on this host machine (dns server). for example dig @dns.domain.lan client1.domain.lan correctly resolves domain name.

I've been learning linux for a while now with half an eye on making a career out of it in future. One sizeable gap in my knowledge at the moment is networking. Is it feasible/desirable to set up a network of virtual machines to use as an environment to learn networking? My budget is non-existent so I was hoping to be able to get a basic understanding of the principles from installing a few desktops, a virtual gateway etc on VMware workstation on my laptop, and doing a lot of reading online.
Is this feasible, or will I just end up learning about virtual networks instead of real ones? Also how much power would be required, because my 3GB RAM lappy has just gone bang and all I have now is a (new) 1GB RAM lappy.

I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.
My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.

Why I can install amd64 programs and why I get unknown for the uname -p command?

I have read the wiki and several online tutorials and still cannot get my machines to talk to each other over NFS.Both are amd64 with Debian testing. Tutorials invoke programs that do not exist in testing, instructions are inadequate or too old.

I'm running kernel release 2.6.26-2-686 on a i686 and are trying to share files between my machine and some Windows 95/98 machines. When I enter smb://ip_number/share_name in Nautilus, it works. I can browse the files. When I try the same with smbclient or smbmount, it complains.
smbclient -I=ip_number -L=//server/share gives cli_rpc_pipe_open: cli_nt_create failed on pipe srvsvc to machine tf_calibration. Error was ERRSRV - ERRerror (Non-specific error code.)

I'm trying to setup, GimPhoto.

I am running ubuntu 10.04 on an amd 64bit laptop.Trying to run the deb file provided but is mentioned when opened in GDebi package manager that "Error: Wrong architecture 'i386'" which makes sense. There is not 64bit version. But provides the following instructions.

1. Download GimPhoto 1.4.3 for Linux Debian Package (deb), from this locations: GimPhoto 1.4.3 Debian Package (deb)
2. Install it using Gdebi OR Double-click it from Nautilus. For user with 64 bits system that using Debian Package (DEB) follow instructions below

The correct path/location is critical. I always download everything into a "media" folder. Keep this in mind for your own installation ... your path has to be 100% correct." When I open a terminal and cd to my downloads folders, and run the following.

I have a rented vserver running at Strato [URL]. It came preinstalled with Debian 7. I upgraded it to Debian 8, what seemed to run fine, all services running. The problems came up when I tried to reboot the server to test the init system. It just does not come up, I cannot ping it, nothing. I can boot into the rescue system, mount the system partitions and chroot in to the filesystem. In this state I also can run my services, including apache2 and mysql. In the syslog I find nothing about the reboot. Now I need to reboot ino the normal system. I already tried to resume to sysvinit without success.

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.

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?

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?

How can i get a RAID virtual image disk?
What i need is to mount several directories from any other partiton (or file system) as a new merge file system that can grow or decrease depending on the free space. As if it was a dinamic RAID,so i can work with huge files distributed over the partitions mounted.
Ejemp: /mnt/sda1/dir_raid1 + /home/dir_raid2 + /mnt/sda3/dir_raid3 ---> /mnt/RAID/
mhddfs and unionfs <---- are not the solution im searching (cant use huge files)

I have a debian squeeze box with dual NICs that I'm trying to configure with two virtual hosts. I'd like to have one of these machines act as a router for the 2nd NIC so I can plug in a switch and have a separate subnet.
Something like:
- Openwrt router 192.168.1.1 (firewall/vpn/stats for 192.168.1.0/24 domain)
- KVM machine with 2 NICs (192.168.1.2)
- Virtual machine #1 has a fixed IP of 192.168.1.3 (virtual nic)
- Virtual machine #2 has a fixed IP of 192.168.1.4 (virtual nic) but also controls the 2nd nic and routes 192.168.80.0/24
I'd like to use the 192.168.80.0/24 network for testing equipment without poisoning my existing network.

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.

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.
