similar to: console access for domU owners

My dom0 is uing Centos 5.2 x64. I have just upgraded Xen from 3.3.0 to 3.3.1. After upgraded, I find that I cannot hotplug additional vcpu anymore. I have a domU "linux1" which is a paravirtualized vm with centos 5.2. I try to "xm vcpu-set linux1 4", it does not have any error message, but those vcpu cannot be displayed. I also tried to add vcpu using "virsh setvcpus

All, Is there a way to setup serial communication between dom0 and domU. The idea is to have some way of exchanging messages between dom0 and domUs. Certainly, it is possible to use s host-only network, and ssh or shared file system to exchange data. However, there could be cases where the dom0 is not networked. You may want to automate configuring domUs from dom0. Any suggestions. Arijit

Hi all, I were upgrading my system recently. But I met some difficult problems, the biggest one is described in http://permalink.gmane.org/gmane.comp.emulators.xen.user/66971, unfortunately I got no answer yet.

Moi! I upgraded Xen-2.0.1 to Xen-2.0.5 (testing) and everything compiled cleanly. I''m still able to boot dom0 and start domUs but networking doesn''t work anymore. xen-br0 appears in dom0, but vif-interfaces now only when ifconfig -a is used. Interface appears in domU and all seems to be fine, except no any data doesn''t move in any direction. I can''t even ping

Hello, I''ve come across a strange problem when installing a particular software package in a domU. I''m trying to install DigiChat (http://www.digichat.com/downloads.html) and the process is immediately killed. I have installed the package with no problems in a VMware VM, UML and native. ...Even installed into a UML, then copied the entire filesystem over and created a domU

For some reason I can''t find it in the wiki, faq, man pages, or manual. If I connect using ''xm console'', how do I disconnect? My domU is Ubuntu6.06 Server.

I''ve been working on a xen-unstable tree from mid-April. I wanted to upgrade to the latest version, so here is what I did: - Clone a fresh copy of xeno-unstable.bk (1.1507) - "make world" - Change the .config of linux-2.6.11-xen0 to include my ethernet card (CONFIG_FORCEDETH=y) - Add localversion files to linux-2.6.11-xen0 and linux-2.6.11-xenU - rm -rf the existing dist

Back in January there was a mail thread on this subject ( http://lists.xensource.com/archives/html/xen-devel/2005-01/msg00659.html ), however I see that blkfront still does not include ioctl support for disk geometry. So, any application that uses "sfdisk -g" to get the geometry of a partition, or disk, will fail when run in DomU. Is this a deliberate omission? Nick Logan

Hello, is there a way to start automatically the vncviewer when a domU starts? When I was using the xm toolstack I could use "xm create domain.cfg -vncviewer" or something similar (if I''m not wrong), but I don''t know how to do it with the xl toolstack. At the moment, I have to create the domain using xl create domU.cfg, then xl list to see the domU id and then xl

Hi all, Currently we have severe problem and are struggling to investigate it. The problem is data broken. Reproduce pocess is following, 0. test FTP function between guest domain and FTP client(other PC). 1. put data from FTP client to guest domain. 2. get data from guest domain to FTP client. 3. compare put data and get data on FTP client. 4. repeat process from step1 to step3.

xend will not start a domain if one of the block devices is currently mounted elsewhere, but it will not detect if the device is currently attached to a loopback device. I wouldn''t have thought this a problem, provided that the loop device itself wasn''t in use, but it causes all sorts of strange things to happen. My loop device was mounted with the following command

I spun a new xen kernel from pristine sources using modules, had the APCI errors and scsi timeouts. I took pristine source and spun a monolithic kernel and everything appears to be working. gcc version 3.4.4 20050721 (Red Hat 3.4.4-2) if it matter. xen_changeset : Wed Oct 26 11:59:13 2005 +0100 7500:20d1a79ebe31 I have had this APCI issue on this SMP Athlon with modules for a while now.

Hi all, I installed a paravirt CentOS 5.4 domU on a CentOS 5.4 dom0 environment. I compiled the domU kernel with framebuff console. But I couldn’t using VNC to connect to the domU console. The kernel boot message could print on the vnc console. But after the boot process, the console appears on the text console in dom0 again. The configfile is as follows: vfb = [

Hello list! I''ve noticed this problem a couple of times now.. so I''m wondering if it''s a known bug? Symptoms: After "long" dom0 uptime (174 days when it happened now, was something similar on previous times too) cannot start new pv domUs anymore.. pygrub runs and boots the kernel, but kernel newer gets to actually running initrd and the console output

I have an FC6 dom0 running on a headless server. I want to install a CentOS 4.4 domU with a console accessed using vnc from a remote machine. I *think* I should be able to do this from my understanding of the documentation. I''ve configured a domU to boot from an ISO image to do the CentOS install and run xm create. netstat on dom0 shows there''s a listener on 0.0.0.0:5900, but

Hello, I''ve noticed that if I try to restart Xend via "/etc/init.d/xend stop" then "/etc/init.d/xend start", I won''t receive any errors but then when trying to execute "xm" commands after the restart I get error asking if Xend is started. Is there anything else I need to make sure gets stopped/started with Xend? Another question ... domU reboots

Hi, I''m running Nevada 75a configured as dom0. I added a domU HVM running Nevada 75a, on a Sun X4600 with 8 ADM Dual cores. I can get the domU installed and configured, however, I can not get any network connectivity. I followed the steps accoding to documents on Open Solaris. I also followed some of the threads of the list to verify the configuration, but I can not fix the
