Subject: Re: [HTCondor-users] Help: How to use VM Universe? Thank you
Thank you for your reply.
I have already modified the BIOS setup of the server in order to support the virtualization. And now I make sure the kvm is running now.
And I also modified the condor_config file to support the vm, and the HasVM parameter is True .
The submit file is as follows:
universe = vm
executable = kvm_sample_job
log = sample.vm.log
vm_type = kvm
vm_memory = 2048
# should_transfer_files = YES
# when_to_transfer_output = ON_EXIT
# transfer_input_files = /data/linux_OS_ISO/CentOS-6.4-x86_64-bin-DVD1.iso
# /data/kvmswap.img
# vm_cdrom_files=/data/linux_OS_ISO/CentOS-6.4-x86_64-bin-DVD1.iso
# vm_should_transfer_cdrom_files=True
vm_checkpoint=True
vm_disk=/data/kvmswap.img:sda2:w:ext4
ext4 is not an image format. e.g. raw, qcow, qcow2 are image formats. In general, it's usually not needed unless it's raw.
# kvm_cdrom_device=/media/cdrom
queue
After I condor_submit this file. The result of condor_q -better-analyze id of this job is:
The Requirements _expression_ for your job reduces to these conditions:

[15] 48 TARGET.VM_Memory >= 2048

However ,I get the message from /var/log/condor/ShadowLog as follows:

I google the keyword VMGAHP_ERR_JOBCLASSAD_KVM_INVALID_DISK_PARAM, but I get nothing useful.
The parameter of vm_disk in the submiting file is /data/kvmswap.img, it is created with the following command:
dd if=/dev/zero of=kvm_swap.img count=1000000
mkfs.ext4 kvm_swap.img
Can somebody tell me how to solve this problem ?
Or give me an sampe submit file ?
Thanks a lot.

There in black-and-white is why your job isn't running.
* You asked it to run only on machines which are advertising HasVM = True.
None of them match this condition.
* You asked it to run only on machines which have VM_Type == "kvm". None do.
* You asked it to run only on machines where VM_AvailNum > 0. None do.
* You asked it to run on machines with >=75GB of disk space. None do.
It hints that only 1.7GB is actually free.
* You asked it to run only on machines with VM_Memory >= 2048. None do.
You clearly need to make config changes on your *execution* nodes to give
them the capability to run VMs, and to announce this capability in their
MachineAd.
> It seems that the kvm is not running?
Of course not. Condor hasn't found any machine in your cluster which is
suitable to run this job, so it hasn't started anywhere.
So let's go back to your original mail:
"I want to use VM Universe. And follwing the instruction."
Which instruction exactly are you follwing? Give the URL. I suspect you
have missed out a huge chunk.
Regards,
Brian.
