Hello, I have installed rpm version of xen 3.4.3+ libvirt 0.7.0-6 on my server with Centos 5.4 (kernel 2.6.18-238.12.1.el5xen) When I run reboot a domU (para virtualized Linux) by command "virsh reboot [vm]", sometimes domU cannot be rebooted but sometimes can, pattern is random.

Hi friends, I''m developing an architecture using xenbus/xenstore that use DomID to read/write informations over a shared memory with dom0. But always that i restart my DomUs the DomID is increased. I''d like to use always the same DomID for the VMs. Any option? Thanks -- Luciano Barreto _______________________________________________ Xen-users mailing list

Does anyone know if it is possible to 'hide' a grub menuentry with CentOS 7 ? I have a custom menuentry that I don't want to be seen on the grub screen - but it needs to be selectable as the entry to boot via 'grub2-reboot' I've scanned the grub2 documentation - but I can't find anything obvious - so I'm guessing it can't be done - unless someone knows

Hi all, I''m doing my first xen, running with 3 domU perfect. I need to know which way to backup domU to restore these to another server if i''ve problem with this machine. There are 3 LVM with 10G in VolGroup01 for each domU, with each of these partitions: /dev/xvda3            8,7G  1,4G  6,9G  17%

I installed CentOS 7 on a Shuttle X27D box (dual-core Atom 330), and so far it seems to work fine, but it didn't set up a Grub2 entry for the existing Windows XP installation in the first partition (MBR). Running os-prober generates no output. fdisk shows that the NTFS partition is still present as /dev/sda1, and still has the bootable flag set. I added a menuentry for Windows to the end of

Hello Xen folks, I use Debian Squeeze. I want to passthrough PCI devices. With the old stable Debian (grub legacy) i did not have problems. I edit /etc/default/grub like: quote: GRUB_CMDLINE_XEN_DEFAULT="quiet xen-pciback.permissive xen-pciback.hide=(00:14.2)(01:05.1)" I run "update-grub". Now i look at /boot/grub/grub.cfg: ### BEGIN /etc/grub.d/20_linux_xen

Hello CentOS users, in the recent time I keep getting the logwatch warnings from my 2 dedicated servers running CentOS 7.4.1708. I guess because of the numerous kernel updates (because of Spectre+Meltdown) in the near past? Could someone please suggest me, which files in my /boot partition would be safe to delete? I would like to avoid the situation of having to boot the rescue partiton etc.

I''m trying to run Xen on Arch Linux with UEFI boot. I followed the steps for Xen in the Arch Linux Wiki https://wiki.archlinux.org/index.php/Xen I get the following when attempting to boot: Loading Xen 4.2.2 ... WARNING: no console will be available to the OS Loading Linux linux ... Loading initial ramdisk ... Unfortunately there is no console so I cannot determine what has gone wrong,

You get these if you install Debian Wheezy as HVM and then try to convert to PV. This is Debian bug #603391.

Hey Guys ! I am trying to install Xen 4.0.1 on Ubuntu 10.04 LTS on a 64-bit machine. Basically the issue that I am facing is that when I try to boot up my Domain0, my video display driver crashes and the system simply hangs. I am using an Intel graphics card: $ lspci -v | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) I

I've been trying to use memdisk with grub2 to boot some iso images -( I've done this without any problem with pxe ) There is a memdisk.mod in /boot/grub/ and I've seen some material talking about this, but no example of a menu. After trying countless permutations - Right now I have : menuentry "Memtest-Plus 4.2" { echo `hello` insmod lvm

Confirmed this issue. To reproduce: Install a fresh Wheezy AMD64 guest under Xen 4.1 (hypervirtualized, boot from the debian-7.1.0-amd64-CD-1.iso). Use "entire disk" automatic layout for partitioning, this creates /dev/xvda1 for / and /dev/xvda5 for swap. It will create /boot/grub/grub.cfg with many references to (/dev/xvda,msdos1) which works fine when the machine is booted

If this has already been done, please forgive me. However, if not, I''d like to submit this as a mechanism for generating a bootable grub2 stanza for hypervisors. As the /etc/grub.d/* files rely on defaults in /etc/default/grub, I added the following Xen specific variable: GRUB_CMDLINE_XEN_DEFAULT="console=com1 115200,8n1 dom0_mem=512M dom0_max_vcpus=1 dom0_vcpus_pin=true

I recently updated the kernel on an Ubuntu 11.04 PVM domU. The dom0 is an up to date Debian Squeeze host (Xen 4.0.1). Attempting to start the domU after this with xm create gives "Error: Boot loader didn''t return any data!". I ran pygrub against the domU manually, I got the following: Traceback (most recent call last): File "/usr/lib/xen-default/bin/pygrub", line

I have a laptop with windows 10. I went into the Windows disk manager and shrunk the volume to make room for C7. That worked. I also changed the BIOS from secure boot to "both" (secure/legacy) I installed C7, went fine. About the time it was done I realized I never saw anything about "other" boot options (seems I saw that in the past). Anyway sure enough, got done and C7
