KVM: 'ÿ' character after starting a VM via virt-install
by gibbe gabba 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/… [View More]

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 … [View More]

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 … [View More]
