CentOS 5 Server :: Centos 5.4 And Xen 3.4.2 Full Virtualization Not Working
Mar 31, 2010
I installed the latest version of Centos 5.4.It came with Xen version 3.0.2 I think.I am running it on a Dell R510. It supports hardware virtualization.I was able to virtualize Windows XP and Windows 2003 server on it by selecting the install from DVD option.I was having problems trying to get a PCI DekTek card seen by the virtualized Windows domains so I tried to upgrade XEN to 3.4.2.I used the repos available from Gitmo and it went easy.
The only problem is now that when I try to create a "New virtual host" it only allows me to use HTTP, FTP option and not the iso or DVD option. They are greyed out. I was wondering if anyone has had this problem and might know a work around for the Xen 3.4.2 problem. Perhaps a better location for the kernel or something.
I have centos 5.3 with text console onl, not X server, now I try install solaris 10 at xen with full virtualization (hvm)
Now I have some like "zombie domain"
How I can to kill this? If I reboot the server it doesn't help.
No fonts found; this probably means that the fontconfig library is not correctly configured. You may need to edit the fonts.conf configuration file. More information about fontconfig can be found in the fontconfig(3) manual page and on [url] Domain installation does not appear to have been successful. If it was, you can restart your domain by running 'virsh start solhvm123'; otherwise, please restart your installation.
Do you know what this a problem?
If I chagne --vnc to --sdl and run below command on my desktop to appear windows and disappear for 1-3 seconds, virt-install -n solekhvm3 --ram 1024 --hvm --disk path=/dev/vol1/solek --sdl --cdrom /dev/cdrom --os-variant solaris10 --force
I have a customer who has (currently) three servers running Centos 5.5, one running Windoze 2003 and around thirty or so workstations running XP Pro.
I've just been reading about RedHat's product - RHEVD and was wondering of anyone knows if this product (or anything similar) is aavailable under CentOS.
Basically what we need to be able to do is to virtualize the XP workstations so that the staff can connect via a browser (inside the office or off-site - or for that matter anywhere) and be presented with a standard desktop.
I know I can achieve this using Citrix XenDesktop or VMWare View but I would prefer to use a FOSS solution if one exists. Having said that it has to be robust and well past Beta
The word on all lips are "virtualization" so I decided to smell this flavor. I have a machine running CentOS 5.3 64bit and I have unlimited access to this machine, but I don't want to reach it physically. Is it possible to install and maintain a virtual medium using ssh or other remote connection? When I installed the OS I have selected the packets regarding the virtualization, but now from where can I start? Is somewhere a guide for doing this?
I had just put the last touch on a snort, mysql, apache, barnyard, base isntall to CentOs 5.3. I noticed that ifconfig displayed an odd virtual nic, and I wanted as little running on this machine as possible. I don't remember specifying that I wanted XEN installed. And on the old lowend machine that is powering this server, Virtualization was the last thing I wanted running on it. I did a google, discovered that the way to remove XEN completely (yum uninstall xen' only removed 'xen' but still, oddly, xen was running after a reboot. Talk about perplexing.
first of all, ill provide you with the package name i got [URL]...i went to /usr/src/redhat/SOURCES/bwbar-1.2.2 did ./configure ; make
then i get this problem : [root@server bwbar-1.2.2]# ./bwbar ./bwbar: /usr/local/lib/libpng12.so.0: no version information available (required by ./bwbar) i have installed libpng & libpng-devel
[Code]...
after looking around a bit i thought it would be better to get the sources from kernel.org directly and try to compile that one, but then i found it to have the exact same error. would be very nice if someone could direct me to a solution for this. i have the bwbar already installed on another server which runs CENTOS 4 , i installed it there AGES ago , so i dont really remember what was my method back then.
the CENTOS 5 server dose not like me installing bwbar on it for some reason. maybe its bwbar's fault?, im no coder so i hope anyone that got a clue could check this out for me.
i'm a familiar with Linux environement ( fedora 10 user ) and i got a project in a training where i have to create a cluster with two nodes where i have to set up a number of VMs that will run applications such as ( Samba, Ldap, Zimbra, ...) but i don't know how to virtualize on top of a cluster ! i would like to know how that can be done, and how is it possible to let the VMs get ressources ( RAM & CPU ) from the two nodes ??
I chose virtualization when installing Centos 5.3. The kernel I got is 2.6.18-128.el5xen My plan is to use KVM, I disable xend service. I don't need a xen enabled kernel. How do I update the kernel to a non xen one?
I have been setup a PDC with samba+ldap, is working, smbldap-tools working, I can create users, add machines, etc, really cool.Now I have seen MDS from Mandriva, cool tool to handle my network, I try to setup MDS, but looks like something is not good. I have follow the instructions from their site, I access the web page, but went I input my username + password my browser wait for ever and never receive any answer. It suppose that u have input the LDAP username and password from the admin. I had run the mmc-agent daemon as stand alone to see what is doing, but I see any issue:
I've got Cent 5.6 using centos-ds.x86_64 8.1.0-1.el5.centos.2 installed via yum.
I turned on the memberof plugin, here's the section from dse.ldif:
I'm currently messing with the value on memberofgroupattr. The only thing that seems to do anything is with it set the way above, in the error log I get:
So if I'm understanding, it's trying to mod the user entry and the attribute isn't allowed.
Setting the memberofgroupattr to anything else gets me nothing noticeable. ldapsearch isn't showing memberof:
I've run the fixup-memberof.pl in /usr/lib64/dirsrv/slapd-hostname and I get:
I'm using ldapadmin from a Windows box to assign/delete people from groups. What I'm a little confused on is the difference between a group and a groupofuniquenames. I also see a difference when using the web gui (directory server gateway) in users. The gateway creates and entry while in ldapadmin I'm creating users. Not sure how that factors but the memberofgroupattr relies on what object class it is and I'm obviously trying the wrong things or something is busted elsewhere.
The error log isn't showing any other errors.
I can restart dirsrv just fine, nothing funny in the log when I do that:
I am using Cent Os 5. I want to know that is there any way to check that how much size of squid cache directory is full? Normally when squid size will reach upto 2GB then I have to clean it.
# cache_dir ufs /var/spool/squid 2000 16 256
I assign 2000 MB to the cache size. One month have been pass while squid is running but i am unable to know how to check the current status of my squid cache size.
I am trying to figure out how to get an almost bare metal virtualization running, and having a hard time getting it going I tryied the Virtual Machine manager, but it wont let me do full virtualization.
If you select "support virtualization" during install, you get the xen kernel installed.
Some things do not work with this kernel (e.g. nVidia drivers). So my question is whether it is possible to install both kernels (xen and ordinary) and select between them with grub at boot time?
I did try this a while ago, by first installing with xen and then manualy adding the ordinary kernel, but the ordinary kernel failed to boot (for reasons I don't now recall - sorry). Clearly, there must be differences in the "virtualization" build other than the kernel.
The alternative, if I want to play with virtualization, would be to have two entirely separate installations, but this seems like a waste of space when surely almost everything must be identical?
I can't find anything in the Centos Xen documentation about this.
Before I try again I would just like to check if anyone actually knows if this is possible, or if not why not?
I have CentOS 5.5 and try to create KVM virtual machine with CentOS 5.5 as a guest. But when I exec command: virt-install --connect qemu:///system --name test --ram 1024 --file=/var/lib/libvirt/images/test.img --file-size=10 --vnc --cdrom=/var/lib/libvirt/images/CentOS-5.5-x86_64-bin-DVD-1of2.iso --vncport=10000 --accelerate --os-type=linux --nonsparse --livecd --hvm

I'm no expert on DHCP. My problem is that i have a CentOS 5.5 server on which i want to install a DHCP server. I have two NICs where eth0 has access to the internet and where eth1 should act as an DHCP server.
I have installed dhcpd and this is how my dhcpd.conf file looks like.
Code:
ifconfig looks like this
Code:
When i start dhcpd on eth1 i get no error messages but when i connect any devices to eth1 they don't get any IP. I cant find anything in any logs about devices trying to get an IP address. I dont have any firewall rules in iptables.
i am trying to get centos 5.4 installed and bootable on my 16gb flash drive, with persistent overlay using and ext3 formatted drive.i want to be able to boot into centos and be able to have all updates from yum, etc, saved when shutting down for my situation i cannot use vfat.

I installed vsftpd server in one of my servers using "yum install vsftpd" command. NFS server is running in the other server and mounted as "/data" in this FTP server. root in FTP server has also root authority in NFS server. All the files and sub-folders under "/data" in FTP server have 755 or 766 mode. Even I modified vsftpd setting to allow root login.
When I login as root to FTP server with FileZilla client, I can see all the file list in root home directory and move to /data directory. I can download any file in a local HDD but I can not download any file in /data directory.

it seems the skype not working as i was unable to see this user's status as logged in from another skype account on a different system the architecture is: CentOS release 5.3 (Final) uname -r : kernel- .6.18-128.1.6.el5 uname -a: Linux localhost.localdomain 2.6.18-128.1.6.el5 #1 SMP Wed Apr 1 09:19:18 EDT 2009 i686 i686 i386 GNU/Linux
Agere got purchased by LSI and now LSI tech support claims there is no Linux driver for this card even though the literature clearly states the availability of a Linux driver.I have installed the firewire driver mentioned in other forum posts from ELRepo.
I am setting up a new server with 2 nics installed. Nic0 goes to the firewall and nic1 goes to the internal engineering network.
Problem is Ip forwarding is not working!
Particulars: Server Name - slick Firewall Name - gateone engineering node - crooked
Routing on slick:
From crooked ( which is inside the server (slick) with an ip address of xx.xx.221.249 the only way I can ping or anything outside of the firewall ( gateone) is to turn on IPtables with this configuration:
I don't want to use IPtables. I need the ip forwarding to work.
