Then I believe this should be fixed: users should be able to run
libvirtd without brctl installed. I can still use QEMU/KVM before on
my machine without it, so I find no reason why it stop working now
with virt-install.
OK, now I install bridge-utils, and run libvirtd. After that, I tried
virt-install, but still got error like below:
# virt-install -c qemu:///system --name jeos2 --ram 500 --file
img.jeos2 --cdrom jeos-8.04.1-jeos-i386.iso

Traceback (most recent call last):

File "/usr/bin/virt-install", line 345, in main
conn = cli.getConnection(options.connect)

return libvirt.open(connect)

libvirtError: virConnectOpen() failed
How to fix this now?
Thanks a lot,
