Re: kernel 3.9.x kvm hangs after seabios
Ok, the cpu stays at 0% when it hangs, there is only one 100% cpu peak
which happens when the vm starts ( I think this is quite normal).
However I run following command, and I stop it right when it hangs:
anakin trace2 # virsh start vm-jack; pid=`virsh qemu-monitor-command
vm-jack --hmp info cpus | grep '\*' | awk '{print $5}' | cut -d\=
-f2`; trace-cmd record -P $pid -p function
if anyone is interested it produces a 1.6 GB file (the compressed
version can be found here: http://papan.sk/share/trace2.dat.tar.gz
(150 MB))

[gentoo-user]
Hello all, I have a router (asus wl500gp with openwrt kamikaze 7.09) with samba server version 2.0.10-4. I have used smbfs to mount this router on my gentoo-box (everything works fine), but since kernel version 2.6.27 smbfs will be removed I have to switch now to the cifs modul. The problem is that I am able to write but I cannot read (I'm always getting permission denied, when I'm trying to read, writing is working fine). I'm thinking that cifs cannot work with such a old samba version. If you have some experience with cifs and samba please verify my assumption. Here is some configuration files smb.cfg: [global] syslog = 0 syslog only = yes workgroup = lan server string = Samba Server security = share encrypt passwords = yes guest account = nobody local master = yes name resolve order = lmhosts hosts bcast [home] comment = /home path = /home browseable = yes public = yes guest ok = yes writeable = yes my /etc/fstab: //samba-srv/home /mnt/samba-srv cifs guest,rw,uid=1000,gid=100,user,defaults 0 0 Thanks Best Regards Tomas -- tomas dot papan at gmail dot com

I notice a video freeze every 1-2 seconds or so, then the video snaps back to where it should be. The audio sounds fine. Mplayer often spits out a warning message[1]. I also noticed that typing into forms (like an email in Gmail) in Firefox, after Firefox has been running a few hours also suffers from this freeze every 1-2 seconds.
