Fedora Servers :: Libvir: QEMU Error : Out Of Memory?
Jun 11, 2009
Has anyone seen this error in libvirtd?libvir: QEMU error : out of memoryWhatever it is, I'm pretty sure that's what's keeping my virt-manager from working. There's 12GB of DDR3 on this box, so I really really hope that it's not actually a memory problem. This here is a brand-new whitebox I build just for virtualization on F11. Can anyone here help me make it work?
Edit: This is a 64-bit install. All 12GB are accessible by the OS.

I'd like to learn it. So I installed lenny & grub2, after that win7, reconfigured grub2, upgraded to squeeze. All is fine, but I cant start working in Debian as I can work only in Windows. So I decided to use qemu to emulate win7 booting. I have sda1, sda2 for squeeze; sda3 and sda4 for win7. If I try "qemu /dev/sda3" I get disk read error. If I try "qemu /dev/sda" I have grub 2 boot screen and when continue booting win7 I get "Ramdisk device creation failed due to insufficient memory" (as screen on [UR:]). I tried to use m -1024 parameter and got screen with "Windows load files" and reboot to grub2 screen/

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 &

I'm looking at the Memory settings in virt-manager, and it seems that the Maximum allocation setting implies that the assigned memory for the VM can expand up to that amount (e.g. 512MB). Currently I have 128MB set as the change allocation, which is reported in the VM, and 512MB as the maximum allocation. If I fill up a tmpfs ramdisk past 128MB, the VM kills all new processes until I force the current allocation to 512MB and unmount the ramdisk. I can then return the assigned memory to 128MB. I'm hoping that there's a tool that I'm overlooking that will automatically increase and decrease the amount of memory within the maximum setting.

I have been setting up a vps I got out with bhost.net, with CentOS installed. I've been learning and have set up everying I need with the exception of ftp/sftp.
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'm running Fedora 11 (2.6.30.10-105.2.4.fc11.i686.PAE) 8 GB memory on a AMD Phenom(tm) II X4 965 Processor, 4 core server I just built.The problem I have run into is any virtual machine that has >1024 MB memory assigned to it will not boot. As along as it has 1024 MB or less it boots fine.The symptom you see is a very quick message "Booting from hard disk" the screen then goes blank, you can't login through SSH, and can't ping the network address so I know it's not some crazy video problem hiding the boot process.The attachment are messages from a failed boot attempt.

I am having a problem with lockups on a new FC12 box (dual core 3 ghz, 4 gb memory,HDPVR,nvidia 8400gs). This happens reliably when replaying MythTV videos, but also randomly at other times using other apps (I suspect also boot but I can't be sure; it just occasionally stalls part way through the boot display).
Usually but not always this is accompanied by a kernel panic (caps lock + scroll lock lights flash on keyboard).
I did a core dump with kdump and it reports:
Thread 1 (<main task>):
Cannot access memory at address 0xffff880028025b70
I am in the process of running memtest86+ right now, and it's been through several passes without errors. I know it needs to run more, but given the reliability of this problem with MythTV video playback I am wondering if the problem could be in the video card memory.
Does anyone know of a linux (or bootable) tester for video memory? All I am able to find are some things for windoze like this.
Also is there any way to track that address from the core dump back to a physical location?

After patiently waiting for 30+ hours during install attempts with the "Virtual Machine Manager", I realized that it wasn't going to happen. So then I read about a possibly working version, qemu-kvm How to use this to get a VM install up and going ? For instance, this command appears to begin an install, but where does it actually create a vm image from that?
qemu-kvm -m 512 -cdrom /iso/Fedora-14-i386-DVD.iso

I'm running a Windows 7 guest using Virtual Machine Manager to launch my "console" to the VM. I believe it uses VNC to connect to the console. I'd like to have clipboard synchronization so I can copy from the host and paste to the guest.

I just install QEMU and virtual machine manager to use virtualization, but virt-manager cannot run properly. I can create a VM, then mount CDROM ISO, startup. With Windows installation, it runs well until format partition step, after that it is disconected and exit with error related to VNC. I dont know why have this problem cause the packages that I installed is from Fedora repo and I think they have been tested.
Here are some infos:
Fedora 14 - kernel 2.6.35.6-45.fc14.i686.PAE
qemu-2:0.13.0-0.7.rc1.fc14.i686
libvirt-0.8.3-2.fc14.i686
virt-manager-0.8.5-1.fc14.noarch

Anyone familiar with QEMU? I'm attempting to load F15 for testing purposes along with REL 6. This is what happens, all goes well until it is actually starts downloading files to the virtual disk which appears to work until it gets to about 1/2 way completed, then it hard crashes(actually shuts the machine down). Also I had to turn of ACPI because when it is enabled it just hangs the VM altogether. I'm wondering if I should also turn off APIC?
Is there some way of loading a VM in verbose mode or debug mode to see what is happening and maybe causing this hard crash. The log files for QEMU shows nothing other then the normal loading of the virtual machine, its given name, source ISO and things of that nature.

Is anyone familiar with how to correct a glitch with Qemu-KVM that prevents virtual machines (Windows Server guests) from starting after the Linux host has been rebooted? It gives an error constructing a domain in /dev/sr0 because of /usr/share/virt-manager/virtManager/engine.py line 493 [run_domain vm_startup], /usr/share/virt-manager/virtManager/domain.py line 573 [startup self.vm create()] and /usr/lib/python2.6/site-packages/libvirt.py line 287 [create if ret=-1 raise libvirtError].

I'm trying to make some pages. For this I try to host them locally. However, when I have an error in my PHP code, the server shows an internal error 500 page and doesn't show on what line and what compile error it encountered. There is no such information in the error log either. What should I do about it, it's not really nice to comment all the lines and then try to uncomment them one by one. I've been googling for a while, but didn't find anything.. I forgot to mention, I;m using Fedora :P, the apache that came with it and mysql and php from the repository...

I'm running Fedora x86_64. I need to setup a virtual machine to do some work on ARM platform. Thus, I've installed QEMU.
Code:
qemu --version
QEMU emulator version 0.13.0 (qemu-kvm-0.13.0), Copyright (c) 2003-2008 Fabrice Bellard
Then, I have dowloaded an ISO image of Debian 6.0 armel.Following instructions on official wiki, I have first created an empty disk image,
Code:
qemu-img create -f qcow debian-armel.img 650M
then I have attempted to boot from ISO image;
Code:
qemu -m 512 -hda debian-armel.img -cdrom debian-6.0.1a-armel-CD-1.iso -boot d
Boot process hangs with the message:
Code:
Booting from cdrom...
639 medium detected
Boot failed: Could not read from CDROM (code 0004)
No bootable device
link refers to Fedora 12, but it seems still unresolved...

I have run into an issue with Fedora on my laptop that has me stumped. On this laptop I had partitioned the hard drive with Windows 7 (came with the PC), and initially Fedora 13. This setup worked fine for about four-five months, but recently Fedora will no longer boot. One day I attempted to load the OS and after GRUB get a screen that says "Error 28: Selected item cannot fit into memory." Windows continues to load fine however, and a memtest worked fine as well. When I attempted to run my Fedora 13 live-cd, I got the similar error "Error 28: Not enough memory to load this specified image."
Now, not having anything critical on the Unix partition, I decided to delete the Fedora partitions and start from scratch. I did so and the computer successfully loads a Fedora 14 live-cd albeit slowly (but still not the 13 one... I'm guessing the CD is just corrupted from scratches). Unfortunately, once I installed Fedora 14 on the empty space and tried running, I get my original error dealing with the item not fitting into memory. I'm out of ideas, and getting tired of the machine being Windows only.
The specs are as follows:
ASUS UL80VT Notebook
Intel U7300 1.3Ghz
4GB Ram
GRUB reports memory as:
607K lower / 14272 upper

I have a Ubuntu 10.04 LTS and about 40 ThinClients running LSTP in a school's computer lab. Everytime the users start to use applications, the server's memory utilization increases, while the swap memory is quite free. I have 12GB of memory on that server.
