[CentOS-virt] KVM: 'ÿ' character after sta rting a VM via virt-install
I'm unable to start a virtual machine with KVM.

Re: [CentOS-virt] KVM: 'ÿ' character after sta rting a VM via virt-install
Just curious as to what hardware you're running it on. And when you say you've installed the necessary rpms, does this mean you installed KVM by hand after the install, or through the installer when you first installed it?

Hola, para resolver esta situación te aconsejo que modifiques un fichero que se encuentra en: nano /etc/sysconfig/iptables Si se modifica ese fichero (siguiendo sus reglas) al volver a iniciar/reiniciar el servicio/demonio de iptables se activarán los cambios, y esos cambios también estarán al reiniciar el sistema.

I use kSar as well as Munin. Munin's only problem is that it has a
hard coded 5 minute granularity - which is perfectly fine for 99% or
more of what you need. I run this script on my systems which keeps
sar logs with finer granularity that I can check into with kSar if I
need to. But I almost never need to.
Run this every hour from cron to keep sar files for each hour

You may choose to only turn this on at times when you need that kind
of granularity - below is pretty extreme with 10 second granularity.
But even at that I do not find it impacts performance in any noticable
fashion.

kSar runs on your local desktop and connects via SSH to the remote server and collects the sysstat data. It's good for checking or reviewing server stats once in a while.

You only need the client up to the point where you get the network set up. Then you can switch to a better native remote access method directly to the guest target, like ssh/freenx for Centos, remote desktop/vnc for windows - just like you would with a physical machine. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

You may want to check that nfsnobody is defined on your system and
rpc.idmapd is actually running. Also the output from rpcinfo might help.

I'd probably want to keep things simple while you are testing. Perhaps
cut this back to:
inf1:/ /test rw,noatime,sync,hard,intr 0 0
Running tcpdump at both ends while you try to do a directory listing may
provide some insight (which process is waiting for a response from whom)
Err grasping at straws ... you may also want to check for any old stuff
you may have in /etc/hosts.{allow,deny}.
Hope this helps,

Hi People,
Thanks for all the responses related to this.
To keep things simple I started from scratch. Just working on the
server and testing my mounting using the server itself and this is what
I have found
/etc/fstab
*** other unrelevant entries *
/home/nfs4exports/homenone bind,rw0 0
/tmp /nfs4exports/tmp none bind,rw0 0
inf1:/ /media/nfs4 nfs4 auto,rw 0 0
inf1:/nfs4exports/home /media/nfs nfs auto,rw 0 0
When I mount /media/nfs everything works as I would expect and I am
seeing the files I expect
When I mount /media/nfs4 the mount completes and I can see files but
they are not the ones I expect
ls -lsa /media/nfs4/home/
total 20
8 drwxr-xr-x 2 root root 4096 Apr 27 13:36 .
8 drwxr-xr-x 5 root root 4096 Apr 27 13:22 ..
4 -rw-r--r-- 1 root root0 Apr 27 13:36 home-test
ls -lsa /media/nfs/
total 24
8 drwxr-xr-x 3 root root 4096 Apr 21 14:21 .
8 drwxr-xr-x 4 root root 4096 Apr 27 12:40 ..
8 drwx-- 2 clintd clintd 4096 Apr 27 15:23 clintd
The home-test file is a test file I created inside /nfs4exports/home
so it appears that NFS v3 sees and uses a bind mounted area as you would
expect whereas NFS v4 is ignoring the bind and using the filesystem
underneath which is very strange as all the reading I have done suggests
that you now must now have bind configured for NFS v4 to work correctly.
Thank you for any insight you can offer.
