Hello, I''ve recently setup a Linux Dom0 with a 3.0.17 kernel and Xen 4.1.2, and since the 3.x series doesn''t have blktap support I''m using qdisk to attach raw images. I''ve been playing with small images, something like 1GB, and everything seemed fine, speed was not fantastic but it was ok. Today I''ve set up a bigger machine, with a 20GB raw hdd and the

Note that vbd/1/5632 is still there

Hi all, I have a following problem: - Remus network buffering doesn''t work.

I have an issue on Xen 4.2+ (now on yesterday''s tip) where when I try to use an iso image as cdrom for a pv domU, it appears that the devices is an unusable state on the domU side. DomU kernel output: http://bpaste.net/show/63482/ xen logs: http://bpaste.net/show/63490/ udevadm monitor output: http://bpaste.net/show/63481/ I can work around this issue easily by creating a loop back

Are there any tools like iptraf or top to display tc stats? I would like to see things like flowes(TCP or UDP connections) as well as simple per second stats. I''m trying to monitor my p2p uploads and network connections to see if things are getting into the right class. I used to use mrtg for this, with some perl scripts I wrote. This project of mine has long since bitrotten.

Hi, List, I''m trying xl create a pv guest with qcow/qcow2 image, it always fails at libxl_device_disk_local_attach. #xl create pv_config_file libxl: error: libxl.c:1119:libxl_device_disk_local_attach: cannot locally attach a qdisk image if the format is not raw libxl: error: libxl_create.c:467:do_domain_create: failed to run bootloader: -3 disk configuration is: disk=[

Hello! I was asking for help on the Freenode channel, and I was pointed here. I have a situation where, using xl, I can create a functional PV domU, with or without pv-grub, but I cannot access the console. Firing up xend and using xm works without trouble. Since xend and company is being deprecated, I would like to transition to using the xl toolstack. The system is an Arch Linux system

Hi all, I’m running Xen 4.1 on a couple of NetBSD dom0s and NetBSD’s pkgsrc provides both the xl and xm tools for working with Xen 4.1. I understand that xl is the new way of doing things, but I can’t get it to create my guests the way I want and the main symptom of this is that the text console isn’t available. When I create a guest with xl it starts up qemu-dm (which xm doesn’t do) and I get

From: Stefano Stabellini <stefano.stabellini@eu.citrix.com> When disk is a cdrom and the drive is empty the "params" node in xenstore might be missing completely: cope with it instead of segfaulting.

Hi, I am following http://xenbits.xen.org/docs/unstable/misc/vtpm.txt, but I''m having some problems when I try to start vtpmmgr-stubdom I''m using Xen 4.3 on Ubuntu 12.04 and I have a physical TPM. The config file for vTPM manager is: kernel="/usr/local/lib/xen/boot/vtpmmgr-stubdom.gz" memory=16 disk=["file:/var/vtpmmgr-stubdom.img,hda,w"]

Package: xen-utils-common Version: 4.4.1-6 Severity: normal Dear Maintainer, (There appear to be several reports on the BTS with concerns relating to this report. Some unarchiving/merging may be necessary. Reassignment may be needed as well since I'm not sure which package this problem would fall under. Ultimately decided to file with xen-utils-common with 'xl' being the frontend

Hey all! Just a reminder, the CentOS Virt SIG meeting is tomorrow, 2pm, on #centos-devel (freenode IRC). Agenda items I've got: * Xen 4.4.1 for C6 update (finally) - Got xen 4.4.1 w/ updated XenServer blktap working, + libvirt - Other changes to consider: xend off by default, revert "favor qdisk" change * oVirt joining SIG? * Meetings over Christmas - proposal: Cancel phone

Since when we are using the m2p_override it is not true anymore that the mmap''ed area doesn''t have corresponsing struct pages. Removing the VM_PFNMAP flag makes get_user_pages work on the mmap''ed user vma. An example test case would be using a Xen userspace block backend (QDISK) on a file on NFS using O_DIRECT. The patch should be backported back to 2.6.38.

Thanks Jim, Looking at the logs for the working and non-working setups, the command line for QEMU is identical and the qmp commands almost the same: they both do "query-chardev" and "query-vnc" and the working setup does an additional "qmp_capabilities" which is likely not relevant. So I guess it must be in QEMU - I'll head over to the bug tracker. Thanks

The time has come for another round of stable releases. Please send (or resend) any outstanding backport requests for 4.0.4 and 4.1.3 before Friday 20 April. Note that 4.0.4 will likely be the last release in the 4.0.x branch. Ian.
