similar to: HVM read only HD image

Hi All, I sent the patch to allow blktap to be able to booted as system bolume for PV-on-HVM. However, there was a problem that hdN and xvdN were not able to be specified at the same time. I made the patch to correct it as follows. - Whether hdN is defined first is checked. - If hdN is defined, xvdN is not replaced with hdN.

Hi All, I sent the patch to make blktap work with PV-on-HVM. I corrected the part that had been pointed out in the Xen community. ・All xvdN disk is looked like hdN. ・All tap disks are checked.(tap:aio, tap:sync, tap:vmdk, etc.) We cannot use blktap for the volume of the system with PV-on-HVM and are embarrassed. Could you apply this patch? Or, please give the comment to me. Signed-off-by:

Hi, I have been trying to create a xen HVM Centos4.4 image on centos 5 with a DRBD filesystem installing from DVD. However I get an IO error on the filesystem during the centos installation process which then aborts. The DRBD filesystem seem to be setup correctly and is functioning as a block device as I can mkfs -t ext3 /dev/drbd1 read and write without error. If I replace the disk

Kip, Does the problem with Xen 3.1 in HVM/Intel manifest as those BTX halted errors (e.g. http://lists.xensource.com/archives/html/xen-users/2006-10/msg00014.html) ? If so, do you happen to know whether this problem has been solved in Xen 3.2 or 3.2.1? This message of yours was written this March, so I'm assuming that 3.2.1 will contain this fix? Can anybody confirm this? I'm having

hello, I would like to map (Read/Write) pages owned by a HVM guest from my Dom0 Linux kernel module. I have access to the "machine frame numbers" of these pages. 1. What is the right interface to do this? kmap needs ''struct page'' ptrs which I doubt exist for pages owned by a HVM guest. Is there a hypercall to do this then? 2. Do I need to modify the HVM behavior in

Hi, I''ve got a qemu image of a linux distribution which works perfectly on KVM and basic Qemu, however when I boot it with Xen HVM, it says "Booting from Hard Disk failed FATAL: No Bootable Device" My disk portion in the config file "cdrom = ''/dev/sr0'' root = ''/dev/sda1 w'' disk = [ ''file:///data1/vdisk.img,sda1,w'',

Hi, When using lapic as timer source the hypervisor delivers timer interrupts late. In the source xen/arch/x86/hvm/vpt.c function create_periodic_time creates a timer element with a "bonus" of 50% of the desired time until the interrupt: pt->scheduled = NOW() + period; /* * Offset LAPIC ticks from other timer ticks. Otherwise guests which use * LAPIC ticks for

Hi all I''m running CentOS 5.1 x64 + Xen 3.0 & I have setup a CentOS 5.1 x64 domU as a HMV. For the setup I used VNC, but I would prefer to be able to access it via "xm console cPanel" via SSH directly. Here''s the output cPanel HVM: [root@pc-00059 ~]# more /etc/xen/cPanel name = "cPanel" uuid = "ff940501-507d-04ca-e590-831e79ba0397" maxmem =

Hi, This set of patches remarkably accelerates IDE PIO on HVM/IA64. I got a throughput of 2.11MB/sec in disk read performance. Without it, it was only 64kB/sec. I posted the prototype once. http://lists.xensource.com/archives/html/xen-devel/2006-12/msg00077.html The basic idea is to add a buffering mechanism in a hypervisor. I know this approach is not sophisticated. But there is no other good

Hi, I''ve run linux off an on for several years. Recently I''ve been using windows (simply for ease), but have gotten so fed up with stability and what not. I had read good things about xen, so I installed suse and was hoping to not give up the 10% of things that I need windows for. I''ve still got windows on a partition and was wondering if I could boot that, but wanted

Hi All, When xm block-detach command was done on PV-ON-HVM, the response of other disks was lost. It is because a wrong event channel was invalidated when detaching it. Not the evtchn number but the irq number is invalidated specifying it.

Hi folks, i have a problem to boot an Ubuntu CD in a hvm-enabled machine. I get a black screen when connecting via vnc to the virtual machine. When i change the line cdrom= to some other CD (grml Live CD, Windows CD, other ones) it runs fine. But any Ubuntu CD (kubuntu alternative, ubuntu server, ubuntu desktop) i get the mentioned error. I tried using sdl (no window opens) and with

Newbie here. My hardware supports HVM (full virtualization), but I only need to run Linux on it. I initially tried to create a HVM domU, but couldn''t get pciback to work with a telephony card I need for use with Asterisk. However everything seems to be working fine under a paravirtualized guest as long as I use permissive mode on the card. (Knock on wood-I''ve had some weird

Greetings xen gurus... I''m working with xen-3.0-testing downloaded on July 3, 2006. I have configured an hvm domain and want to use vif-route and network-route to configure the communication. The domU starts up fine. I was able to complete the installation of the OS (RHES3) and can restart the domain repeatedly. However, I cannot ping the network interface from dom0 using the

Hi, we have a debian etch system running here and it works fine for hvms (winxp) and paras (debian etchs). Today i tried to do a SLES10SP2 setup as hvm (in the future it should run as para).

Hi, Sorry, I should not have removed infomation on xend. image.py, line 399, in configVNC config.remove([''vncpasswd'', vncpasswd_vmconfig]) When vncpasswd is removed, qemu-dm cannot be started in reboot of hvm domain. Because necessary information disappears. It cannot be helped though information in config list remains in xenstore. This patch corrects above. Regards,

Hi All, The interface of the evtchn has been changed as follows. ・xen-unstable.hg : cs13198 [PV-ON-HVM] Update evtchn interface to match new PV Linux interfaces. ・xen-unstable.hg : cs13197 [LINUX] Extend the event-channel interfaces to provide helper methods However, the following errors occur if pv-on-hvm is done in insmod. This patch corrected this issue. --- # insmod xen-vbd.ko
