Hi, I use xen on debian linux systems of several years in some HP ProLiant servers. Processors of these machines are of last generation and have support for virtualization. I could then use xen with hvm mode rather than paravirtualization mode? I benefit? p.s. sorry for my bad english. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
hi, i have 3 installation, live at clients, running since a year now, without any problems at all! xen server 4.0.1 **************** hp dl 320G6 debian squeeze 6.0.1 2.6.32-5 disk lvm2 grub2 windows driver: http://www.meadowcourt.org/downloads/gplpv_Vista2008x64_0.11.0.238.msi the only thing is, you have to disable digital signing in windows, so it will appear on the screen "WINDOWS TEST MODE" I am now trieng to get xen 4.2/2.6.39.3 running because I need a remus/drbd HA box. windows hvm works but run into problems with squeeze guests. thanks walter. *** name = ''server01-srv-08r2-ads001'' kernel = ''/usr/lib/xen/boot/hvmloader'' builder = ''hvm'' device_model = ''/usr/lib64/xen/bin/qemu-dm'' maxmem = 2048 memory = 2048 vcpus = 2 acpi = 1 apic = 1 vif = [''bridge=eth0''] disk = [''phy:/dev/vgmain/lv_server01,hda,w''] boot = ''cd'' usbdevice = ''tablet'' vnc = 1 #vncunused = 0 vnclisten = ''0.0.0.0'' #vncdisplay = 2 #vncconsole = 1 #vncpasswd = ''123456'' vncviewer = 1 sdl = 0 stdvga = 1 serial = ''pty'' ne2000 = "1" on_poweroff = ''destroy'' on_reboot = ''restart'' on_crash = ''restart'' *** -----Original Message----- From: xen-users-bounces@lists.xensource.com [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Mauro Sent: Freitag, 22.

Hi Mauro, 1) Yes, you can create hardware virtual machine (HVM) 2) The only real benefit is that you can execute unmodified operating system on your xen platform, in other words, you can run operating system not ported to xen (without para-virtualization support, for ex.: Windows) under your xen-based platform 3) Change debian with Slackware :-P Il 22/07/2011 14:15, Mauro ha scritto:> Hi, I use xen on debian linux systems of several years in some HP > ProLiant servers. > Processors of these machines are of last generation and have support > for virtualization. > I could then use xen with hvm mode rather than paravirtualization mode? > I benefit? > > p.s. sorry for my bad english. > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

You can run Linux as HVM virtual machine too, but the I/O performance will be significantly reduced. However, it''s possible to use PVonHVM drivers for the I/O devices and get better performance (my guess is it should be more or less on par wirh PVM). If you are used to PVM (paravirtualized virtual machines) and there''s no problem with PVM drawbacks, I would say that there''s no need to experiment with HVM Linux machines.

iain, thank''s for the hint, i will have a look on those drivers, need them first to test, otherwise my clients hang''m higher :-) by the way, have you got experience in 4.2 unstable, 2.6.39-3, lvm2 and squeeze guest''s? windows guests works flawless but squeeze guest''s make me headache since 3 week''s time already! thanks walter -----Original Message----- From: Iain Kay [mailto:spam@iainkay.com] Sent: Freitag, 22.

Is your issue networking related e.g. the squeeze VM can''t get an IP or ping the dom0?

hi iain, it is block device related. to install debian squeeze guest on xen 4.2 unstable I have to define the disk first as "sda". *** disk = [ ''phy:/dev/vgmain/lv_server01,sda,w'',''file:/var/xen/kanotix64-2.6.38.iso,hdc: cdrom,r'' ] ** then after the install manager wants to reboot I have to change the xen config into "had". *** disk = [ ''phy:/dev/vgmain/lv_server01,hda,w'',''file:/var/xen/kanotix64-2.6.38.iso,hdc: cdrom,r'' ] *** on earlier installation, like xen 4.0.1, 2.6.32-5 amd64 the debian squeeze guest''s see the disk with fdisk -l as - xvda1, xvdan-1, xvdan in my 4.2 unstable environment the booting process just hangs. I posted already several description to the xen-list. I think it is a grub2 problem, but can''t find the glue. *** name = ''server01'' kernel = ''hvmloader'' builder = ''hvm'' device_model = ''qemu-dm'' maxmem = 1024 memory = 1024 vcpus = 1 acpi = 1 apic = 1 uuid = ''06ed00fe-1001-4fc4-b5d8-11993ee4a8b9'' vif = [ ''bridge=br0,mac=00:16:3e:1a:b3:4b'' ] #vfb = [ ''type=vnc,vnclisten=0.0.0.0,vncunused=0,vncdisplay=1'' ] disk = [ ''phy:/dev/vgmain/lv_server01,hda,w'',''file:/var/xen/kanotix64-2.6.38.iso,hdc: cdrom,r'' ] boot = ''dc'' usbdevice = ''tablet'' sdl = 0 stdvga = 1 serial = ''pty'' on_poweroff = ''destroy'' on_reboot = ''restart'' on_crash = ''restart'' vnc = 1 vnclisten = ''0.0.0.0'' vncviewer = 1 *** -----Original Message----- From: xen-users-bounces@lists.xensource.com [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Iain Kay Sent: Freitag, 22.

I run only linux guests, so in terms of performances is better paravirtualized or hvm?> 3) Change debian with Slackware :-PWhy? I love debian :-) _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
