similar to: Gathering "metal" stats

Hello. I have been doing some performance tests with Xen and CentOS and have found some strange statistics when comparing the virtual memory (/proc/vmstat) and I/O (/proc/diskstat) statistics between the Domain 0 and guests. When I look at the "pgpgin" statistic it is exactly the same as the "read sectors" in Dom0. However, when I look at the same statistics in the guest,

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, I have an IBM xseries 345, running CentOS 5.3, hosting a few Xen domUs. However, I need more RAM -- but cannot remember if all (four) RAM sockets are populated (which would mean to buy higher capacity modules) or if there are two slots left to use. However, I'd like (and think that it's possible, but don't remember how) to

I''m trying to get DHCP working with DomU clients. I don''t want to use libvirtd. There''s a dhcpd on the machine and it works fine for all clients in the network, but not for DomUs. If I set a static IP on the DomU all networking for them is fine, so there''s no general networking problem. I use the xen 3.2 packages for CentOS on CentOS 5.1. There was a public

Hi, I ''ve got a CentOS 5.2 server running xen 3.0 with 2 DomUs also running CentOS 5.2. All my boxes are up-to date. I''m experiencing trouble with networking. Dom0 can reach the outside world when no DomU are started. It can also reach the outside world when only one DomU is running. The troubles begin when I start the second DomU. At first, this new DomU, called DomU2,

Hello, I''m used to using Xen in a bridge mode where my dom0 and all domUs are on the same layer 2 network. However now I have to set up a server whose eth0 is on one network and the domUs will be on another /29. So, for example, if the eth0 of dom0 is 192.168.1.214/24, then I have 10.1.1.0/29 (10.1.1.0 -> 10.1.1.7) routed to it for use in domUs, how would I go about setting that up?

Is there a way to run a script on my samba PDC machine when a user logs in and logs out? Thanks in advance. -- Air conditioners and Computers are the same - they both crash when you open Windows.

Hi! How do i create consistent snapshots of VM''s from Dom0?.

Hi, I have some problems with my OpenVPN server in a Xen DomU. OpenVPN works fantastic but theres a problem connecting other DomUs on this server. I have the following iptable rule to forward the requests to the internet. iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j MASQUERADE This works fine. I can connect to other DomUs on the same server but they can''t answer the

hey list, we are currently migrating our users from novell to samba. now we have one problem: in novell we could give e.g. user1 access to users2 home share so he could modify, delete or add files on this share. in samba we defined a global homes share that is mapped on logon. so how can we give user1 the needed rights? here is the definition of the homes share in smb.conf: [homes]

I have been using PXELINUX, with "LOCALBOOT 0" when wanting to boot from disk, for many years. Now on new Dell Optiplex 990 machines, PXE boot with "LOCALBOOT 0" hangs after message Booting from local disk... without the expected "Exiting PXE" message. I tried "LOCALBOOT -1" and some other values also, none seemed to work. I tested SYSLINUX 4.04.

I have created a DLL not so long ago using C code. My code used the IntegerFromString() function that used to be exported in the Rinternals.h header file (and thus easily accessible). Recently I upgraded to R 2.5.0 and my DLL stopped working. I see that the IntegerFromString() function is not exported in any of the header files in the RHOME\include directory. Is it possible for me to use it

Hello you all out there Does anybody know the definite guide to create a dummy ethernet device? So, what I want to have is an ethernet device, without a physical link, or so called a dummy device.

Hi, I have a Centos5 machine running xen 3.0.3-41 with two NICs each on its own subnet: 192.168.1.x and 192.168.0.x. All DomUs can talk to each other OK through two xen bridges. There are 3 DomUs: Dom0, Dom1 and Dom2 The scenario: I''m trying to capture packets on Dom2 on 192.168.0.x from external devices that are sending SIP stuff to Dom1, but fail to capture any packets.

I have been using PXELINUX for a while and appreciate all you guys are doing! I have a couple of questions re PXELINUX: 1. I am experiencing problems with the LOCALBOOT statement on an IBM x3650.
