View Full Version : kvm created guest crashes

19th January 2009, 09:06 AM
fully updated fedora 10 host. issue number one is that using virtual machine manager during setup of the kvm based guest the second networking option (use physical device) is totally greyed out so. I googled this and did see a few similar posts (none fedora related) but no good answer. well whatever I chose the first option networking and go through the entire install for a centos 5.2 guest which seems to work fine. till it says "reboot". ok I hit yes hoping it will pop back up like a real machine and let me finish the install. hmm I wait a few minutes, ok its not coming back. so I try to start the machine and the startup screen flashes for about 1 second and the machine switches to powered off. I can see it quickly in top starting and then clunk its off. here are a few messages (have no idea what they mean) from tail /var/log/messages. btw I know there is a vibr0 (virtual adapter???) shown from ifconfig -a set (automatically) to and I put my centos guest on my network...I have no idea if that is part of the issue.

has anyone tried using kvm here? I know my fedora 10 book hypes it and says redhat bought the company but from what I am seeing here it is not usable...from the greyed out network #2 option to the crashing of the guest making it impossible to complete the install.

any suggestions are greatly appreciated. thanks.

does anyone here use kvm on fedora 10 and have it working?

I have XPsp3, 2000 and W2k3 serer running ok under KVM. The KVM setup also loads dnsmasq to dhcp an address to the client. Maybe it gets upset if you have taken the address it uses ? It also modify's the iptables rules to masquerade the addresses

[robert@sun ~]$ ps -ef|grep dnsmasq
