CentOS 5 :: KVM With Windows 2008 Guest - ACPI Conflict
Mar 12, 2009
Centos version: 2.6.18-92.el5
Processor:Intel Xeon L5420 Quad-Core
Guest OS:Windows Server 2008 Web
KVM is istalled using these instructions: [URL] When I run qemu-kvm to boot a VM off the Windows Install .iso with the -no-acpi parameter the VM displays the following:
Windows Boot Manager
Windows failed to start...
Status 0xc0000225
Info: Windows failed to load because the firmware (BIOS) is not ACPI compatible
Without the -no-acpi parameter, the Windows Server 2008 guest shows a blue screen with "stop: 0x000000A5" meaning "The ACPI Bios in this system is not fully compliant to the specification." [URL] 386/32bit and x86/64bit versions of CentOs both exhibit the problem. IT WORKS after I compiled and installed the latest versions of the Kernel (2.6.28.7) and KVM (84) (Using these instructions: [URL] Following advice [URL] I really don't want to run a custom kernel. I compiled various KVM versions with the 2.6.18 kernel but still get the ACPI problem or compiler errors or "Hypervisor too old: KVM_CAP_USER_MEMORY extension not supported" How to get a Windows Server 2008 guest running in KVM on Centos?
I have Windows 2008R2 Server acting as Domain Controller for Windows7/XP clients. and CentOS 5.3 Installed configured as Samba Server, I want to make it as ADS member server so any user to login to any machine, and be able to access their Samba share.
I am running an application that requires use of my /etc/hosts file. In it, I have my machine name and its LAN ip address. The program creates a service on a specific port, then attempts to connect to it based on the host name. So my hosts file has to be correct.I added the nameservers to resolv.conf and now my application will not run. My guess is that the computer is checking the name servers first, timing out then checking the hosts file.Is there a way I can tell the system to check the hosts file first, then DNS. I thought it should behave that way by default, but it does not appear to.
Having trouble rebooting a system. Have a Ubuntu 9.10 (2.6.31-16 generic-pae) build on a VMWare installation. The system was fine until I rebooted after an update. Now I get the above message and the system halts loading. Have tried to Grub acpi=off and acpi=force to no avail.
When I run OpenSUSE from the Live CD using normal settings, booting stops with a blank screen a moment after the kernel is loaded. When running it with ACPI disabled, it works, but direct rendering is disabled, even though it detects my video card (Mobility Radeon HD 5650) correctly Here's the Xorg.0.log file: my xorg log - [URL]
i m on the way to migrate from win 2008 server to centos 5.5. i just bought a new hd and have centos installed on it. my old hd runs win 2008 with SFS file system. now i put the old hd as the second hd under centos so i can copy data from it to new hd (centos). i hv install fuse, fuse-ntfs-3g, dkms on centos but still can't read old hd (sfs). the data is quite big so i really need to read old hd with sfs from centos. how do i do that pls? centos can see old hd as sdb when i run "fdisk -l"
I have Redhat 5 playing nice as it authenticates against windows server 2008. But I ran into issues trying to get Redhat 6 to do it as well.
Here is where I stand on my redhat 6 box:
I have my certificates working between the windows and the redhat box.
From Root user I can SU to an Active Directory user. getent works. I can see all the users info. ldapsearch works with the CA certificate so my SSL handshake is working. I do not suspect cert issues
But when I try to login as active directory on my Redhat 6 box I get told I used an invalid password. The password works just fine on the windows server, so I didn't fat finger anything. I am just confused as to why I can have getent and ldapsearching but can not login.
I have turned off iptables on redhat and the firewall on 2008 server to see if that would change the situation but no luck.
I noted that in Redhat 6 I need to config SSSD rather then NSCD.
Let me know if you need to see my: ldap.conf nsswitch.conf sssd.conf var messages
What I maybe doing wrong or leaving out in my configurations.
I can get a connection to Windows server 2008 using rdesktop 1.6, but after a few seconds the connection is dropped and I get a message of and internal licensing error. I think rdesktop 1.6 uses rdp 5.x, and WIndows server 2008 uses rdp 6, but there must be some way to get a linux terminal server client to connect to Windows Server 2008.
I Installed Ubuntu 9.10 on perfectly working dual boot computer (I have Win7, WinServer 2008 & Mac OSX). After Installation, GRUB consolidated Win7 & WinSer 2008 and just put WinServer2008. Windows 7 totally disappeard. I'm sure it did't go any where, but GRUB did some consolidation and put just WS 2008.
Before Ubuntu 9.1.0 Install my Dual Boot OS are Win7 WinServer 2008 & Mac OS X
After Ubuntu 9.1.0 Install my Dual Boot OS are Ubuntu 9.1.0 Windows Vista Loader - This is WinServer 2008 & Mac OS X
I have problem with login into Windows 2008 server usning rdesktop 1.6. While I'm connect Windows 2008 host, prompts username and password i get an error: "Wrong username or password" but i'm sure that username and pass are correct (I can connect this server using windows Remote Desktop). My OS is Ubuntu 10.04 64-bit.
I was trying to connect to Windows server from 11.04 I knew the connection worked from a Windows 7 PC
terminal services client (rdp or rdpv5)An error has occurred Details: recv: ~Connection reset by peer
Fix I'd forgotten about the Windows server security. Control Panel, System & Security, System Remote Settings, Remote Desktop has 3 radio buttons. I changed from most secure to medium security.
1. I installed Windows server 2008, with Active Directory, DNS, DHCP. 2. I installed Ubuntu 9.10 and joined it to the domain. Everything is ok. I can see the Ubuntu in the active directory, it gets an Ip address from the DHCP. 3. I create a shared folder on the server 2008. 4. I can access the server from Ubuntu ONLY by going to "Connect to Server" and entering the data to connect.
My problem :I would like to have the shared folder showing up when Ubuntu boots up or when the user is logging IN on the Ubuntu host. I have tried many things without success. I know how to do it so this is fine. BUT i would like a user to be able to access the shared folder without having to do anything (especially for users who are not familiar with computers). What is the best way to do it ?
I was particulary suprised to have nothing in my logs regarding an IP address conflict in Linux compared to the windows and its popup !Did I miss something in the logs ? Or is there someting to configure to have it ?Otherwise can I do something to have the date in the dmesg log file ?Here my story about this problem :My linux machine was monitored by Nagios so i've seen some Up/down/up/down phenomene when I came to work this morning. I tried to figured out what's wrong browsing the logs (messages & dmesg & mail/root)... but nothing usefull so far...Then I hearded that a collegue booted a old Windows machine the day before. I checked this machine and there was the classic windows popup regarding a IP address conflict! So that was the problem, the Windows machine have the same IP than de Linux box.I was particulary suprised to have nothing in my logs regarding an IP address conflict in Linux compared to the windows and its popup !Did I miss something in the logs ? Or is there someting to configure to have it ?Otherwise can I do something to have the date in the dmesg log file ?Linux : CentOS 5.4 64bitsWindows : Windows server 2003 32 bits
I have too many problems to join my OpenSuSE 11.2 with Samba 3.5.4 in a Windows 2008 Active directory Forest (MYDOMAIN.LOCAL). I have updated Samba to 3.5.4 after read that default 11.2 version have too many bugs. Now, when I try to join the Domain MYDOMAIN.LOCAL via yast i have only an undebuggable error "unknown error". For yast, my Suse is joined but i'm unable to authenticate, i can't see "MYDOMAIN.LOCAL" at KDM login and if i try to lookup forest i have this error:
Code: wbinfo -u Error looking up domain users but i'm able to retrive ticket via kinit Code: # kinit Administrator Password for Administrator@MYDOMAIN.LOCAL:
[Code]...
have you a samba version tested against Active Directory 2008? can you link me the repository or help me to solve this?
I am trying to mount a shared drive on a Windows Server 2008 machine using a Linux machine (Fedora 13). I try mounting by
# mount //HOSTNAME/SHARENAME /mnt/FOLDER
and I get mount error(13): Permission denied.
I have tried other options like # mount -t nfs //HOSTNAME/SHARENAME /mnt/FOLDER -o username=USERNAME and the same thing with different filesystem types (ntfs, smbfs, cifs).
I have:
checked all firewall configurations. verified security/sharing settings for the drive verified registry keys under HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesNfsSvrParameters verified NFS server is running
I am familiar with Windows Server 2008 but I have never configured a system from scratch on my own. The computer I'm using used to have Windows 7 for sharing folders to a Linux server. I have just switched to Server 2008 and have not been able to mount anymore.
One thing that I think is that I tried setting up an identity mapping solution; however, I do not have a domain controller setup. I am still functioning on a workgroup.
I want to dual boot Windows Server 2008 r2 and Ubuntu 10.10 . First, I installed Server 2008 r2 then Ubuntu. After the installation, Grub only found Ubuntu, and "Windows Recovery Enviroment (loader)" on dev/sda1. The Windows OS is installed on dev/sda2. When i load "Windows Recovery Enviroment (loader)" it does a chdsk, then reboot the PC.
How can i make grub find the Windows OS?
Edit: The partition on dev/sda1 is called System Reserved
I am having issues mounting a share on a Windows 2008 Server from all of our Redhat 4 machines. I am trying to back up files before wiping and upgrading them to 5. I will try and post as much information that I gathered after trying different things. I am a newer hire for this network and a Linux newbie.
The scenario is this:
1. Windows 2008 Active Directory. 2. Redhat Enterprise 4 machines
I have root access and I tried entering at the terminal:
" smbclient -L "servername" -U "username"
get the "password" prompt I enter my password and get:
I check event viewer on the 2008 box and last week was seeing:
Event ID: 4625 Keywords: Audit Failure etc, etc "Account for which Logon failed: Security ID: NULL SID Account name: anonymous Account Domain:MYGROUP Failure Information: Failure Reason: Uknown user name or bad password etc, etc
Now the last couple of days the audit failures have not shown up on the 2008 Server box even though I attempted to log in.
The end users used to just use Konquerer smb://"servername"/"share" and it worked but for some reason starting last week this no longer works. Nothing was changed that I know of, this network is in a sealed classified environment with no external access. All additions to the network are monitored and no unapproved software is installed. The lab is in a vault type environment and only a few people know the combination and alarm pass codes so no chance of somebody adding stuff without me knowing it.
I would think with the locked out message it was an issue with my user account but that works fine on the Windows side so I tried my Linux credentials with no success when trying to mount the directory.
Is there something anybody can suggest Linux or Windows side to check? No user accounts work connecting to the Windows share.
p.s. I am aware the above command is only to see the Windows shares but i get the same thing when I just try and mount using CIFS or SMBFS.
I am useing open suse 11.2 dual boot with windows server 2008. Could anybody give some suggestion do I need to upgrade to open suse 11.3. And How I can deal with that and keep my windows.
I just tried to install CentOS 5.4 on my notebook (HP G42-214BR), I use Windows 7 at the moment.
On the first time I got W7 installed at C: and couldn't istall centos on it. Before trying again I went to Windows and free something like 40GB from C:, but the disc where C: is went from basic to a dynamic disc.
After that I tried to install, and got some errors like:
And the final row was like:
And the installation don't go any further than this. What is going wrong?
What happen if we assign a static IP address to both linux and windows host?Consider host A is a ubuntu machine and host B is a windows machine. I first set a static IP for host A (W.X.Y.Z) and connect to it through ssh. Then I duplicate that IP for host B (W.X.Y.Z).The result was that I could no longer connect to the ubuntu machine!
Problems with xen 3.1.2 creating and installing domU CentOS 5.5 I am trying to do a virt-install --prompt --paravirt, and the install error out while trying to download install RPMs. I have googled for xen centos virt-install and various permutations. I have found similar howtos for 5.4 and 5.3, but they resulted in the same outcome. I did find several posts with similar issues, but no solution was posted.[URL]..
Will there be any issues installing and then subsequently running a Microsoft Windows Server 2008 R2 installation on a VirtualBox VM on a Linux host (Ubuntu 11.04 64-bit)? I require Windows Server 2008 R2 for a course I'm taking, and I dont have any systems to install/deploy it onto.
Host Machine Specs:
Ubuntu 11.04 64-bit 4GB RAM 350GB Disk Space Nvidia Quadro system
Using the following command, I can access a windows 2008 server: rdesktop -u myusername -d mydomain -p - -fP -r sound:local -r disk:myhome=/home/myhome serveraddress
connection works fine, and to start with I can see my local disk "\tsclientmyhome" and navigate around + open files. If I try to delete a file or rename a folder, I get an Error 0x8007048F:The device is not connected.
After this, I can no longer access the local disk. It says: "\tsclientmyhome is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. Attempt to access invalid address." As I understand it, I should be contacting myself about permissions... Can anyone tell me what I need to do on my local ubuntu machine to fix this?
