similar to: What's the benefit and design purpose of Xen Console for HVM guest.

xenconsoled: do not write the pty under serial in xenstore if xenconsoled is handling a consolepath. The idea is that pv consoles use the "console" prefix in xenstore and emulated serials use the "serial" prefix in xenstore. There is no need to write the pty for a pv console under "serial", considering that xenconsoled is already writing the pty under

Hi All, Sorry if this is a stupid question. I am walking into someone else''s xen install, and don''t have access to the host os at the moment. How do I tell just from a domU (with Ubuntu) if it is PV or HVM. I have looked through the forums and documentation and it seems to be very easy to figure this out from dom0, but unfortunately that isn''t possible at the

Thanks for the reply. If we want to have PV kernel for CentOs 7 , are there any guidelines to follow? How we can know before hand itself that this kernel is PV or HVM, without installing kernel?

Thanks for the reply. Sorry for the typo in the earlier mail. I have PV-HVM of CentOS 7 & I need to convert it to PV kernel. Basically here I am trying to see whether my PV_HVM kernel is vulenrable to this issue given in the following link http://seclists.org/oss-sec/2015/q3/212 In the above link, it was mentioned that the PV kernel is not vulnerable to this bug, but HVM is. It didnt say

Hi Everyone, In my HVM guest''s config file, I have given my guest 3 interface. I have called them fw1, fw2 and fw3. I have joined each interface to a bridge on the Dom0. This does appear when I do a "brctl show". However, there are 3 other interfaces also added called tapx.0,tapx.1 and tapx.2 (Where x is the domain ID for the guest). Furthermore, I am only able to run

HVM = fully virtualized. The question is, why are you using fully virtualized domUs? Why not paravirtualized (PV)? >>> On 2008/06/16 at 16:07, Rudi Ahlers <Rudi@SoftDux.com> wrote: Itamar - IspBrasil wrote: > why you''re using hvm ? its slow > > > > Rudi Ahlers wrote: >> Hi all >> >> I''m running CentOS 5.1 x64 + Xen 3.0 & I

Hi, I''m the Mageia XEN packager and during QA, we stumbled into a problem. in fact, we wanted to test Mageia 3 installation on a HVM. so, we had a sparse image and a iso file: [ ''file:/opt/testhvm.img,sda,w'', ''file:/opt/mageialive.iso,hdb:cdrom,r'' ] the live booted, and was able to install to disk, but it never seemed to boot after the install...

xend uses rtl8139, and we want xl to be compatible with xm. Some older operating systems don''t have e1000 drivers, and we want widest compatibility rather than best performance (people who want good performance are best advised to use PV-on-HVM drivers). We''ll probably switch to a new default when switching to upstream qemu, in the Xen 4.2 release cycle. Signed-off-by: Ian

Moving to public discussion... This was found with Xen hypervisor version supporting device unplugging and the domU kernel having net-/blkfront and pci platform built-in (or as module). The block device is defined as hda and the NIC type=ioemu (so theoretically guests without pv support would work, too). Since both drivers are present, the kernel tries to unplug the emulated devices and

Has there been any work done on getting an ACPI fixed event or perhaps a general purpose event delivered to an HVM guest. Whereby, the HVM guests OSPM could consume the event and act accordingly. Or Perhaps better stated how would one go about passing an ACPI fixed event or general purpose event that was raised and consumed by dom0 and subsequently pass the event on to each of the HVM

I am running Xen 4 and want users to be able to install arbitrary HVM images. We want both PV and emulated drivers to appear. The reason for this is for compatibility with images that were prepared for Xen 3.3, which assume emulated devices exist at boot time (particularly for running the boot loader). If I do not specify on the boot line xen_emul_unplug=never, then under some guest OS''s

Hi Everyone, Does anybody have any experience using pfSense on Xen? I would most probably have to use HVM... My idea would be to use PCI-Passthrough to the pfsense DomU, and only make the Dom0 accessable via the pfsense firewall Thanks Jonathan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

hi, I am using xen-unstable version and I can use the serial port to debug DomU openSuSE Linux with kgdb very well. But it doesn''t work when I am trying to debug DomU WinXP with windbg. I happened to find this link http://www.evilbitz.com/2006/12/13/howto-debugging-a-remote-windows-hvm-under-xen-using-windbg/, but it still doesn''t work for me. Any suggestions about this?

Hi, I seem to have an interesting issue with vif-route. This is after an update to Xen 4.2.1, switching from xm to xl. I have 10 PV domUs on the host and two FreeBSD ones. All the PV domUs are now working nicely. Since FreeBSD has always been just slightly broken as PV I chose a HVM domU for those, but with PV drivers. Those PV drivers all blew up now after the upgrade. I''m now trying

Hi, I am trying to setup Xen to use "PV on HVM". For this, I did the following. (1) I followed the tutorial at http://wiki.xensource.com/xenwiki/Fedora13Xen4Tutorial to setup Xen4.0.1 on Fedora13. I am able to run virt-manager and create a Fedora 13 guest. (2) I followed the tutorial at http://bderzhavets.wordpress.com/2010/05/27/pv-on-hvm-at-xen-4-0-on-top-of-fedora-13/to use PV on

Hi, I've been testing the Debian packages ahead of the Debian 7 release (which is very imminent) I believe this is a serious bug[1] in the package, as it appears that HVM networking is broken, or at the very least, requires some undocumented configuration step Specifically: - I can start the HVM domU without any vif - if I attach a vif, the domU will not start Looking at

Andy, OSOL 2009.06 been installed in stub domain (hvm domain) at mentioned Dom0 with 2.6.30 xenified kernel via xen-patches-2.6.30-2.tar.bz2 refuse to activate PV drivers.

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 list, I''ve read about recent efforts to push pv-on-hvm drivers to Linux mainline and I''m curious to know the cause for this. What''s the advantage over using pv_ops directly and booting the kernel paravirtualized? Are there plans to move Linux domUs closer to the KVM way (from an architectural point of view)? Hope you can help. Regards, Markus
