similar to: Troubles Using the serial console

Hey, Does anyone know how I can capture both Xen & Dom0 console output on a "Virtual Serial Port" from HP''s iLO (Integrated Lights-Out) interface? Plain linux is no problem, but combined with Xen it seems to go haywire :-) So far I''ve been combining options and the only thing that actually gave me some output (albeit only the Xen console, not dom0) was this:

Hi- I am having a weird problem with setting dom0 kernel output to the serial console with Xen 3.0.4-1, below is my grub setting. With this setting if I don''t enter the grub menu and have the default boot to the first image, everything works fine and I can get output/input to the serial console. The problem is when I enter the grub menu and select the image to boot from, if I

Hi everyone Ok this is really strange. I''ve been messing around with Xen for the past few weeks on a 32bit test machine and CentOS 5.4 and it''s been working fine. Today I went into the office on a Sunday to install Xen on our server but I had a major problem. The server is a home-build with a Tyan s5211 motherboard with an Intel i3210w chipset CentOS 5.4 64bit installed and

Hi, I am having the following setup: the kernel displays its messages to vga and to ttyS0. This works without xen. When I reboot my system with xen with the following options to xen and vmlinuz, xen.gz com1=115200,8n1 console=com1,vga vmlinuz console=ttyS0,115200 console=tty0 the system hangs up while booting the dom0 kernel. Has anyone such a setup working? The thin is, I want a console on

I previously sent this help request to xen-api rather than xen-users. My apologies for the re-send. ------------------- I am following http://www.gentoo.org/doc/en/xen-guide.xml to build a new box for use as dom0. For the dom0 kernel configu I used as a basis a previous, working config from a non-xen kernel. That previous kernel (2.6.32-gentoo-r7) exhibits no console video problem. My new xen

Hi, my physical machine (Dell PE2650) has two serial ports, the /proc/tty/driver/serial output looks like this under a non-XEN Linux kernel: serinfo:1.0 driver revision: 0: uart:16550A port:000003F8 irq:4 tx:2761 rx:2766 CTS|CD|RI 1: uart:NS16550A port:000002F8 irq:3 tx:58353 rx:2986 RTS|CTS|DTR|DSR|CD|RI 2: uart:16550A port:0000EC80 irq:177 tx:0 rx:0 CTS|DSR|CD 3: uart:unknown port:000002E8

Hi folks, we (the company i am working for) are running several dozens of virtualisation servers using CentOS 6 + Xen4CentOS as the virtualisation infrastructure. With the latest versions of all packages installed [1], we see failures in live-migration of stock-CentOS6 HVM guests, leaving a "Domain-unnamed" on the source host, while the migrated guest runs fine on the target host.

Not the same as the other treath, but also an tty access problem. I have an old an cheap digital camera wich isn't supported by gphoto(2). I can get the program running under wine only it shows me: err:dosfs:DOSFS_CreateCommPort Couldn't open /dev/ttyS0,115200 ! (check permissions) err:file:CreateFileA Couldn't open device 'COM1'!

Hi there, I''ve just built xen & dom0 kernel from gentoo ebuilds (bugs.gentoo.org), but my dom0 kernel crashes during boot. Any help is appreciated.

Hi: recently i am doing fast boot from linux kernel to Xen hypervisor,and vice-versa. it means when linux is running on the real machine, i just want to switch to Xen hypervisor without going through bootloader. both linux and dom0 of Xen using the same filesystem. we boot Xen and the Linux with the following command in grub: title Ubuntu 8.04.2, kernel 2.6.29 root (hd0,7)

Xen-users, I have what I think is a bug in the serial console interaction of Xen and Ubuntu. Essentially, the serial console appears to work just fine until it is passed off to dom 0 from Xen. Then it stops communicating with dom0, but still communicates with Xen, if I use the control-A escape sequence. Google will not show me anything related to this. I have local RS-232 serial console working

I've also had a few Xen systems grub entry issues. I'm not yet sure what triggers the events, but I do think there *may* be a correlation to the "/boot" part. I've found the Xen servers that have "/boot" before any of the the lines like "/boot/xen.gz" ended up missing complete grub entries. Not sure it's 100% true. Anyone else comment? Thanks PJ On

HI, We've started to see several issues with the Xen releases. Going back to basics I've used this guide https://wiki.centos.org/HowTos/Xen/Xen4QuickStart Once the install process is complete the grub.conf looks like this: default=0 timeout=5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title CentOS (3.18.21-17.el6.x86_64) root (hd0,0) kernel /boot/xen.gz

Hello, my name is Viktor. I use kernel-2.6.38.5 as dom0. I can''t get access to console dom0. There is a blank screen after xen-4.1.0.gz loading. But dom0 is loaded and I have got it from ssh and it works fine. I just see nothing at monitor screen. Why? May be I have error in my grub.conf settings, please help!

I''m trying to install xen-3.0.4 from source on a debian sarge (3.1r4) box with dual AMD-64 processors (with the new HVM support, although I don''t think that''s got anything to do with the problem).
