similar to: [LLVMdev] LLVM backend: Treat some function calls specially

Jonas, Why not lower everything to a single call during instruction selection, and then write a machine function pass that translates the normal CALL's into CALL_NATIVE?

Hello, I''m running XEN 3.0.3 on RHEL5 2.6.18-53.1.4.el5xen. I used to start the vm with "xm create myvm -c". I see the boot during a couple of second, then, it freeze. The console is freezed, not the vm, a couple of second later, I can ssh the vm without any problem. "xm console myvm" also display a freezed state. This is an extrat of the console : # xm

I'm using ubuntu 12.04LTS I setup a bridged network: # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet dhcp auto br0 iface br0 inet dhcp bridge_ports eth0 bridge_stp off bridge_fd 0 bridge_maxwait 0 Seems to work. Then I created a virtual machine using Ubuntu's vmbuilder tool like so: vmbuilder

Hello, I am looking for a solution for live backups of running KVM hosts. I recently read this article which highlights the following method: http://www.linux-kvm.com/content/first-look-virtual-machine-online-disk-snapshots-coming-fedora-18 1. virsh snapshot-create-as to create the snapshot 2. cp myvm.qcow2 myvm-backup.qcow2 to copy off the now read-only backing image file 3. virsh

Dear all, Please let me start by indicating that I am not from a technical background, so please be gentle and patient with me. I am trying to get a snapshot from my virtual machines (vm) and the following command works for all of them bar one: # virsh snapshot-create-as --quiesce --no-metadata --domain myvm myvm-state --diskspec vda,file=overlay.qcow2 --disk-only --atomic The only exception is

Hi, I have a CentOS-7 server running KVM but also oVirt. Recently, following updates, VMs not handled by oVirt have been deleting themselves after they shut down. Previously to this, I have not had any problems of this nature. I cannot say whether the problem is coming from oVirt updates or not. I am creating a VM using "virsh define myvm.xml" on the server, starting it through

I'm experimenting with how to attach storage to a guest virtual machine (I sent another message to th elist about that as it's slightly different) Looking in the XML files for my virtual machine, I see this: <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/vm/myvm/tmpeuiVc9.qcow2'/>

Hi Tim, Thank you for the input. I think I follow you. I believe the LowerCall is doing what it needs to do - passing pointer either on the stack or in register as per ABI. The LowerFormalArguments() is where I am stuck. LowerFormalArguments () calls CCInfo.AnalyzeFormalArguments(Ins, CC_XCore), which calls the CC_XCore(). This is where I placed the CCIfByVal<CCPassByVal<0,4>> which

Hi list, I have recently migrated to XCP from Vmware Server 2 and have run into issues importing the VM''s Following citrix''s guide I tried using XenCenter to do the import directly on the vmdk files this resulted in XenCenter logging this error: "Failed to import. ---> System.Exception: Failed to import virtual disk file. ---> System.Xml.XmlException: Root element

Hi Robert, > I tried adding to the XCoreCallingConv.td: > CCIfByVal<CCPassByVal<0,4>> // pushes pointer to the stack This looks sensible to me. After that it comes down to cooperation between XCoreISelLowering's LowerFormalArguments and LowerCall functions. LowerFormalArguments is at the beginning of a function and is responsible for taking arguments out of

Hi - help! I have read through previous threads on the subject of 'byval' e.g. https://groups.google.com/forum/#!topicsearchin/llvm-dev/Exact$20meaning$20of$20byval/llvm-dev/cyRZyXcMCNI https://groups.google.com/forum/#!topicsearchin/llvm-dev/$20byval/llvm-dev/uk4uiK93jeM https://groups.google.com/forum/#!topicsearchin/llvm-dev/byval/llvm-dev/46Tv0lSRwBg and read through code

Hi Kashyap, Thanks for your answer! Unfortunately my use case requires cloning the exact memory state, so I won't be able to use virt-sysprep. But the snapshot command looks like something I could use. Could you suggest how to proceed and create/start a new vm from that snapshot?

Is there any way to get the latest Qemu to run on CentOS 7? I'm looking for a way to create backup snapshots, but the current install says: [root at vhost1 ~]# virsh snapshot-create-as myvm snapshot1 "snapshot1 description" error: Operation not supported: live disk snapshot not supported with this QEMU binary -- Robert

A few library calls are commutable by definition, for example multiplications. I defined them as LibCalls for my architecture. However, I found that arguments are always passed in the order they are generated by Clang thus missing possible optimisations. For example, the following IR code ; Function Attrs: minsize norecurse nounwind optsize readnone define dso_local i16 @multTest(i16 %a, i16

Hi, I''m kinda new to XEN stuff, and I''ve been trying to create a fully virtualized guest on CentOS 5.3 for almost 3 months and no luck yet. I approached this process through several methods, one with virt-install and creating config file manually. Following is what happens when I try to create a guest, and I have included qemu-dm and last part of xend.log logs below too.

As a regular user, member of the libvirt group, I run this command to create a basic VM: virt-install --connect qemu:///system --name=test --ram 2048 --cpu host-model-only --os-variant=win7 --disk /myVM/test --boot cdrom,hd --virt-type kvm --graphics spice --controller scsi,model=virtio-scsi --cdrom=/drawer/myIso/w8.iso It returns an error : --------------------------------- Starting install...

Hello, I'm trying to use the tool virsh of libvirt. I want to manage via CLI a vm on a vmware hypervisor which is hosted on a remote host (Is that what you call the node??). I read a lot of thing on your site but I really don't understand how to do something... I saw that: >virsh edit $your-vm-name I think "$your-vm-name" is the xml file you're talking about? Is it

Dear all, 1) I have a very large matrix of  str(keep)  num [1:153899, 1:3415] -98.6 -95.8 -96.4 -95.8 -98 ... that  I would like to reduce its size to something like str(keep)  num [1:1000, 1:3415] -98.6 -95.8 -96.4 -95.8 -98 ...  or anything similar in size as this is a matrix that needs plotting (so is ok if it is 1000 row, 995, or 1123) I think what I need here is a way of selecting

I''ve been using lvm under centos to create the backing store for domUs and although the performance seems acceptable it has some shortcomings. The biggest of which is the LVM bug which prevents me from removing an lv (it says it is still mounted and it definitely isnt). I thought this was just a centos bug but it appears to be evident in debian and ubuntu too and I really can''t
