similar to: obtaining sysinfo for domU from dom0

Good day. I found that XCP ignores VCPU-params (weight and cap) after VM live migration, as well, as those parameters ignored if changed on running VM. May I as someone with xcp cloud nearly check this bug? Thank you. -- wBR,George. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I'm puzzled why virt-xml-checker rejects minimal config xml if it includes sysinfo element: <domain type='kvm'> <name>example</name> <sysinfo> </sysinfo> </domain> with the following error: Relax-NG validity error : Extra element sysinfo in interleave minimal.xml:3: element sysinfo: Relax-NG validity error : Element domain failed to validate

Hi, I believe I can post this here. I have a domU ( Redhat 6) running in Paravirt mode. When I migrate this domU to another host, looks like the domU is freezing in the other host. When I take it back to original host ,it starts to run normally and this is what can see in dmesg of domU : suspending xenstore... trying to map vcpu_info 0 at ffff88000434b020, mfn b67660, offset 32 cpu 0 using

From: Christian Borntraeger <borntraeger at de.ibm.com> drivers/s390/sysinfo.c uses the store system information intruction to query the system about information of the machine, the LPAR and additional hypervisors. KVM has to implement the host part for this instruction. To avoid code duplication, this patch splits the common definitions from sysinfo.c into a separate header file

Hi, All I''m just new to this list, I''m started to dealing with OSS Xen to XCP migration earlier this week, seem the domUs installed via virt-install are function well, but domUs copied via dom0 are failed during bootup process, finally I realize if I could fix this on my OSS Xen will resolve all. Can I have any suggestion from you please ? *Details* *Source XenHost* OS:

Hi All, Having an issue with xen-4.0-unstable where after completing a live migration, an arp is never sent out to update the switch with the new location of the mac address. Network is configured as per libvirt''s instructions with the xen network-script disabled and the bridge (xenbr0) always up.

Package: xcp-xapi Version: 1.3.2-6 Severity: important Tags: upstream xe vm-memory-target-set does not write new target to /local/domain/ID/memory/target. Balloon in guest domain is expecting this value to be changed to do selfballooning. This breaks 'dynamic memory control' feature. Steps to reproduce: 1) Setup any PV virtual machine with static-memory-min < static-memory-max 2)

Hi, I'm a new users of xen and have two questions. The first one is that I'm looking for methods about inter-domain communication for xen. I know besides network, VMs on the same physical machine can exchange information by event channel and grant table. But are these two ways working in kernel mode as part of drivers, or can I directly use them just like network socket in user

Hello. Is it available a communication interface between Dom0 and DomU to get some parameteres about DomU without connection via ssh? For example i need to get information about IP addresses that are allocated in DomU. I found following mail-thread: http://xen.1045712.n5.nabble.com/How-to-get-domU-IP-address-td2510278.html Keir Fraser said about xenstore, but as i understand to use xenstore

I am new to Xen and want to provide simple communication between my DomU and Dom0 environments. I just need to be able to pass a few bytes of information back and forth between DomU and Dom0 while using some form of event management to know when an update occurs so I can act on it. At first, it appeared that using XenBus and XenStore might be the right solution for this. However, after looking

Hi, all I''m totally new to XCP, so maybe i misunderstood the documentation. I tried to create Debian Squeeze (64-bit) and Ubuntu 10.04 from templates and install them from network installation. For Debian Squeeze (64-bit), I did the followings: 1. First ssh login into XCP host 2. xe vm-install template="Debian Squeeze (64-bit)" new-name-label=lenny-64-netinstall

Hi, ever since I have switched my server from Centos 7 to Fedora 32, asterisk is showing memory issues and no calls are possible. I'm using the asterisk that comes with Fedora; before that, I used a self-compiled version on Centos. The hardware is still the same. Asterisk shows the following message when trying to make a call: WARNING[92530]: pbx.c:4644 increase_call_count: Available

Hi I need to pass an alert message from a kernel module in dom0 to domU kernel(something like a reboot message). How can I do that?

I am reposting this because it's been 2 or 3 weeks. Hello, Hopefully this is the right place to send a question like this... I'm attempting to automate creation of VMs using virt-install and a cloud-init disk image. To get this to work, I need to specify the location of the cloud-init configs by passing smbios key/value pairs. Normally, -smbios is provided to qemu to do this. With

Hi all, the implementation of getpagesize() is broken in klibc. klibc uses sysinfo.mem_unit, which linux interpretes as the memory unit all other memory values returned are to be multiplied with. So it's perfectly ok for the linux sysinfo() to return a mem_unit of '1', which is does if the memory available for this machine fits into the counter. For the unbelievers, have a look in

All, Is there a way to setup serial communication between dom0 and domU. The idea is to have some way of exchanging messages between dom0 and domUs. Certainly, it is possible to use s host-only network, and ssh or shared file system to exchange data. However, there could be cases where the dom0 is not networked. You may want to automate configuring domUs from dom0. Any suggestions. Arijit

Hi, I am running OpenStack Cluster and use libvirt + cgroup to limit vm’s performance https://wiki.openstack.org/InstanceResourceQuota What I am confusing is.. 1. After running a vm instance with some croup limit applied, I can’t find any related cgroup settings. 2. Can I change limit value after instance is running? like change disk_read_iops_sec from 10 to 20. One of the xml file like below.

Hi there, I am new to Xen. Just began trying it out from day-before. I have a CentOS 4.4 install on my hda6 partition. And I have a openSUSE 10.2 install on my hda8 partition. For openSUSE 10.2, I chose the Xen options while installing, and so I have the xen kernels too installed. For CentOS 4.4, I downloaded the Xen 3.0.2 source and compiled from there. (I followed the instructions at this

I have two hosts as Xen Server named host A and host B in the same network. A VM is created on Host A. Host A and B have a shared storage using NFS. While doing migration from host A to host B, how can I see the memory pages being migrated. If I run a small continuous program on the VM residing on host A, will the migration complete first or the sript running will complete first? How can I see
