KVM: 'ÿ' character after starting a VM via virt-install
by gibbe gabba 29 Apr '10

29 Apr '10

I'm unable to start a virtual machine with KVM. I'm using Centos 5.4 I have installed all necessary rpms (to my knowledge), but as you can see from the output (below), the system does not boot the CD-ROM. It just sits there doing nothing: # virt-install --prompt Would you like to use KVM acceleration? (yes or no) yes What is the name of your virtual machine? test How much RAM should be allocated (in megabytes)? 1024 What would you like to use as the disk (file path)? /var/lib/libvirt/images/test.img How large would you like the disk (/var/lib/libvirt/images/test.img) to be (in gigabytes)? 20 What is the install CD-ROM/ISO or URL? /root/CentOS-5.4-i386-bin-1of6.iso Starting install... Creating storage file... | 20 GB 00:00 Creating domain... | 0 B 00:00 Connected to domain test Escape character is ^] ÿ the 'ÿ' character appears after a few seconds, then nothing... Any help is appreciated!

virt-manager connect to remote virtual server xen+ssh
by Ed Heron 22 Apr '10

22 Apr '10

I don't usually install a graphical environment on my servers, so I don't usually use virt-manager. However, I recently put CentOS 5 on my Dell Latitude D820. It has hardware virtualization support, 4G RAM and a 500G HD, so I can carry a virtualization lab around with me. I found the trick of getting a non-active xen VM to show up in virt-manager's list by using virsh edit <VM> and changing the amount of RAM, so that was cool. I'm trying to use virt-manager to manager my other xen based virtualization servers, but I'm unable to successfully connect to them. I am able to connect to the other servers with virsh --connect=xen+ssh://vsrv/, though, so I'm assuming it has something to do with virt-manager. I haven't, yet, found any debug mode, so I'm hoping someone on the list has some suggestions for me. Please, give me some hints as to where to go next in trouble shooting virt-manager connecting to a non-local xen server. Is there a debug mode that I'm missing? -------------------- Ed Heron

Connection stall when connecting to XEN guests
by Peter Hopfgartner 14 Apr '10

14 Apr '10

Hello I have a physical server (Dell Poweredge 1950III) running current CentOS 5.4 x86_64 and the XEN hypervisor, provided by CentOS. This machine has 2 virtual machines installed, both with CentOS 5.4 x86_64. Unfortunatly SSH connections coming both, from an external machine or from DOM0, regularly stall, for a period of some minutes. In other words, while working through SSH, at a given moment everything freezes and after some minutes thaws again. We have several other machines with similar hardware/software configurations, but none of these has similar stalls. Anyway, when attaching the console with "xm console <vm-name>" there are no stalls at all. Does anybody have any suggestion on where to start to trouble shoot this problem? Regards, Peter -- Dott.

Maybe there are some girls on the list you can impress with your unbounded kindness. Who says it's not the right way? Since we're going to start fielding off topic questions to waste everyone's time on a focused list, can you tell me why my foot hurts? I mean, I was just using it normally, like a foot. But now it hurts. Could it be cancer? Fungus? Maybe we can turn CentOS into a foot pain site and extend off topic threads instead of just letting them die after short and quick re-educations that anyone subscribing to a mailing list should be aware of by now. Maybe if all of you tarts who are in such an uproar about this used your time to contribute anything substantial, or anything at all (Luke, Nenad, John), you would have something. Since all of you are just consumers and none of you actually participate in any way other than to complain that someone was "rude", STFU. In the meantime, maybe you should join a Ruby dev list with all of your happiness and smiles. Together, you can change the world! -- Christopher G. Stach II http://ldsys.net/~cgs/
