similar to: Finding VBD id for disks in config file

Hi, I encountered a problem while porting Solaris as a guest OS on Xen. The problem I found is that when frontend vbd driver get unloaded, it will close the vbd interface by changing the state to XenbusStateClosed. This appears to cause the dom0 hotplug scripts to remove the vbd entry from xenstore for the domU guest, preventing the vbd from being re-attached. So, my questions are: + This

I am trying to get PV drivers running on both Centos 5.1 and Centos 5.3 HVMs, my DomU is Centos 5.2 with Xen 3.31. For 5.1 I install the kmod-xenpv RPM but for 5.3 the drivers seem to be built-in. For the network drivers to work I had to unload the Realtek NIC driver and renamed its .ko files to stop it loading. Adding the Xen-Vnif alias to modprobe.conf then got the PV NICs working nicely (Much

Hi, From cset 10921, ioemu: prefix is removed from disk config in /etc/xen/xmexample.hvm. Now HVM VBD driver is available, this thus raises a question: how would HVM domain know if one disk is a qemu-dm disk or a VBD disk? From current implementation, qemu-dm will recognize disk had, hdb, hdc, hdd, and VBD drive can recognize all disk (had~hdd, hde, hdf ...) . So the result is: qemu-dm will

Your config is partly right. But it also needs a Qemu

Hi Guys, Now I am using Xen-4.0.0. I need to attach CDROM from ISO files to vitual machines when they are running. The VMs contain RHEL4.6, Windows Server 2003 32bit and Windows Server 2006 64bit. The disk configuration of the VMs is: disk = [ ''tap:vhd:/guest/SS_test/vhd/hmi-100130.vhd,hda,w''] (1) When I attach a CDROM to RHEL4.6 VM with the command: virsh

If I start a domain with a number of vbd devices, it''s a crap shoot if they''ll all show up in the domU''s /proc/partitions. I''ll eventually see all the devices if I keep rebooting the domU. The value of /local/domain/$DOMID/device/vbd/*/state are all 1 for the missing devices, and 4 for the ones that show up. When it works: domU:~# cat /proc/partitions

Last week, I mentioned an error I was getting, as described below. I''ve seen several mailing list posts describing a similar problem as far back as December, 2005.

In this patch series, libxenstat collects these information and xentop display tem. The change from ver.1 is only libxenstat in order to handle sysfs information. I appreciate any
