I have a query regarding top & virtual memory. When we run top it show VIRT (Virtual Mem), RES (Resident Mem) & SHR (Shared Memory). The total virtual memory of my machine is 4 GBs (2 GB RAM + 2 GB Swap), but still I am able to see a process showing 4000m virtual memory column. what it means, as its show VIRT Mem more than actual available VIRT memory

I installed the latest 10.04.1 server minimal install and enabled the virtualisation option. I compiled enough X so that I could run virt-manager and I was able to create a couple of VMs and run them and manage them, but the problem is that in the graphs in manager, I can only get CPU usage, not Disk or Network IO. The options are greyed out. Am I missing something required for these graphs to work ?
View 1 Replies View Relatedwe found that if we use 'top' to show the memory usage of a server (SuSe Linux 10), we can get virtual memory usage as well as 'Resident memory' usage. For virtual mem or a particular process, it is around 1.1GB, which is large but for resident memory, it only consumes 300MB. Are there anyone who knows what the differences are? I would also like to know whether the difference (1.1GB - 300MB) = 800MB are actually available for use by other applications in the system.

1 change system ip into static and install virtualization group.
2 make one partition where i want to install vitual m/c
3 then vim /etc/exports, in which i give path where is data and give rw permission to all. then restart services of portmap and nfs.
4 then on login with xen kernel and on terminal i give virt-manager command and follow steps. at last i get above error. where i m wrong,clearify me so i make vir m/c .
I have CentOS 5.5 and try to create KVM virtual machine with CentOS 5.5 as a guest. But when I exec command:

I am using malloc and frees a lot in my program. It shows its allocated but when i remove it doesnt show as the memory is removed(I am using the top command to view VIRT memory usage). If this continously grows what would happen to my program (Will it go out of memory?)
View 4 Replies View RelatedI install redhat server at virt-manger and i configure my rpms and others tasks and it works fine.
My question is how to get all configuration and data from this virt-manager server to use it at another PC virt-manager ?
Im trying to find a way in redhat to see if there is a command that could tell me the actual used memory by the system. For example when i do the free command, i want to see the Used minus cached value. Is there a way linux can report the true used memory and not the cached/buffer etc? if there is not specific command for that, can someone tell me a bash script that could calculate used-cached ?

View 3 Replies View RelatedWhen we have Oracle 10g in RedHat, the free memory goes down soon after bootup of the system and never increases. I learnt from various forums that Linux does cache the disk files for the better performance. And when any application requires memory they get the memory and the caching does not block any memory. We want to capture the free memory available for one the harware planning activity.
1) When we use vmstat command, it gives very less free memory. since it caches large size files, the free memory is very low.
2) We tried free command, but how do we know how much actual free memory is available. i.e. excluding the cache usage
I used to use server 64, and it handled memory well with Jaunty and Karmic but with Lucid the memory usage is always high and can't run virtual machines.

I woukld like to know the kernel command or linux kernel file name where i can get the process actual physical RAM usage in linux version 2.6.21 or hiher version.

Using yum I installed vsftpd and ran into problems, thinking it was something I might of done I did a fresh install of CentOS and I still recieve the same problem on a fresh install so it is nothing I have done to the server.
The problem is when connecting via a sftp client I get an out of memory error. This error is listed in the putty faq ( url ) under A.7.5, there is a brief explaintion of the cure under A.7.6.
there is mention of a login script but I don't know where this is located. I'm a novice at Linux but by no means incompotent when it comes to computing.
I have a tested and working ssh connection with my local network server. On Ubuntu it was simple to just add an ssh connection to Virtual Machine Manager to connect to 'hippopatamous.local' (yes thats the name of my server :P) but now that I'm in arch its different. I connect to the server using just 'hippopatamous' and on top of that its like the Virtual machine manager can't connect.
All it says is to make sure that libvirtd is running. I ssh-ed in to the server and make sure it was running. I even ran it on my local computer (this was before I remembered/realized this would be a server type daemon so running it locally wouldn't do anything)
I have tried to install debian 5.0 and 4.0 without any luck. I have both tried virt-manager and virt-install with both debian-501-i386-netinst.iso, and full dvd. I't always gives me the same error:Starting install.Could not find an installable distribution at '/xen/debian-501-i386-netinst.iso'

I downloaded EasyPeasy (EP) to evaluate whether I wanted to put it on my wife's EeePC 900. I thought, why not install it in a virtual machine on my desktop system in order to play with it and see what needs to be done to get all the programs she will need working before I do the actual installation? So, I launched virt-manager, and tried to set up a virtual machine for EP 1.6. Well, it appears to be launching EP, but when it comes up, I have the top bar, but the tabs and lcons that should be on the desktop are nowhere to be found. When I try to shut it down, the shutdown freezes, so I wind up killing the virtual machine after waiting several minutes.
Every time I try to do this, I get the same results. This is whether I choose KVM or QEMU for the virtual machine. I have created it with 1 Gb RAM and 1 processor, then created a 16 Gb virtual drive. I started with 0 pre-allocated for the drive. I tried again one more time but this time actually allocating the full amount of the virtual drive before starting to see if it made any difference. It didn't.
I also noticed that it is not recognizing that I have a DVD with the ISO written to it (it is a bit too big for a CD). There is no option to use a USB thumb-drive or SD card that I can find. So, it appears I am stuck with using the ISO for this installation. It said that there was no disc in /dev/sr0 or /dev/sr1, even though the proper disc was there.
Under advanced options, I have tried both X86_64 and i686 with equally bad results.
For Linux versions, although there is an option for Fedora 13 as a guest, there is not an option for Ubuntu Lucid, from which EasyPeasy 1.6 is derived. I have tried several of the install versions from the list in an effort to get this to work. It didn't.
I have a VM with Windows XP that is driving me crazy. Everything works great except the display windows (and networking, but that is a different story) I am open VirtManager and go to display the OS and the images will get distorted. I will open IE and scroll down a webpage and some of the text will remain still and others will move, leave an image of garbage. This makes it very aggravating to use. To clear the page I can shake the window (using the cursor not my hands) or move from one tab to another till it clears.. then if I scroll again I have to deal with it all over again.
View 1 Replies View RelatedI tried virt-manager 0.8.0-7 or 0.8.1-1, my guest like fedora 12 i386, ubuntu i686, win xp do not have any sound even they detect the driver(es1370 or ac97) correctly. I doubt it is because of the pulseaudio and the qemu's user. Qemu uses not my user, it uses qemu user.
If I uses qemu-kvm directly, it has sound and work fine.
My first post on openSUSE, since migrating from Ubuntu (didn't like Unity!). I've installed the virtualization packages from YAST2 and when I attempt to run virt-manager, it crashes. The error is
Code: could not import gobject (could not find _PyGObject_API object) I've searched both these forums and via a general Google and although I've found posts, all of them are apparently resolved - but not mine.
My laptop is fully up to date and running Gnome 3 on openSUSE 11.4.Has anyone else come across this lately?
i heared that both modules are used to create virtual environment for linux, but what are the comparisons between them which differentiate them could you please explain them in brief .

When I access the guest with ssh and use it from there, it's fast like a real machine. It's only very very slow within virt-manager console. I am using Fedora 14 x86_64.
I have been trying to set up bridged networking, but I keep failing. I am using Fedora 14 x86_64 KDE as host with qemu-kvm and SPICE. The plan is to install a windows server, a few windows clients and then rawhide as guests on that. Naturally I want to use bridged networking for the windows guests.[URL]..But those both leave the guest without internet access. Is it really this difficult, or am I doing it wrong(tm)?

View 2 Replies View RelatedI've been using KVM with great results on Slackware but one thing about Xen 4 that appeals to me is VGA and PCI passthru. I did try to install the Xen Slackbuild some time ago but failed. I'm afraid I can't remember why now. As far as I remember the Slackbuild was just out a day or so, so perhaps there were unresolved issues in the early days. How is Xen now? Does it run as well as KVM, for HVM as well as PV guests? Does virt-manager allow you to create Xen VMs or just KVM VMs? I'm very happy with KVM on Slackware (and Xen on NetBSD) but as I say, the Xen 4 release has some enticing features which pretty much do away with dual- and multi-booting.

I'm running some vm's in FC12 with kvm-qemu and using virt machine manager. I'd like to have some ports automatically forward on startup and be able to add redirections on the fly. Redirection on the fly is talked about here, but I am getting lost on what should be basic instructions.[URL]
As far as startup, In the past I just ran qemu from the cli and manually specified redirection with redir. I can't figure out how to do it with The virt machine manager which I am using to start my VM's now. I do not want the guests to see the host. From cli startup without virt machine manager, it looked like this: qemu -m 256 -hda vm.img -redir tcp:5555::80 -redir tcp:5556::445 &
